Q: Are all baby sleep aids safe for newborn babies?
A: It is important for parents of newborns to refer to the Australian Safe Sleep Guidelines before introducing any baby sleep toy or baby toys into the sleep environment. This organisation recommends infants under 12 months when in a baby cot, baby crib or baby bassinette to be free from loose items such as: blankets, baby pillows, security blankets/baby lovey and toys. The Koolá Doll™ baby comforter is designed for children of all ages (newborns included) and features a multi-functional clip/ teething ring, allowing parents to hang the musical toy koala safely on the outside of the baby crib or cot. Babies can still hear the soothing sleep sounds clearly while staying within a safe sleep environment. This makes it a perfect newborn sleep companion toy for prams, bassinet naps, or daytime routines — a gentle, infant white noise machine alternative that keeps infants comforted and safe.
Q: What makes the Koolá™ Doll different from white noise machines for babies?
A:Unlike standard infant white noise machines that repeat irritating mechanical hums, the Koolá baby sleep toy features a
unique more natural approach with Sing-to-Sleep Technology™ allowing you record your own personal lullaby calming song that plays all night if the parent chooses. Research shows that when babies hear songs sung in the womb, they can recognize and respond to them after birth. We call this the womb song! This helps nurture bonding and supports calming bedtime routines with the reassuring sound of a parent’s voice. Even if a song wasn’t recorded before birth research also shows babies are naturally soothed by their parents voices, creating a reassuring presence that supports bedtime routines, bonding, and gentle sleep-time comfort. Read about the science and discover the benefits of a parent’s pre-recorded voice used on preemie babies and newborns here.
Koolá also includes four additional soundtracks tuned to 528 Hz. Each soundtrack is embedded with a different frequency pulse that align to relaxed and sleep brainwave patterns for example Didgeridoo Melody (Alpha Music 11 Hz), Deep Sleep (Delta 4 Hz) Womb Sounds/Heartbeat (Solfeggio Music Hz) and Harp Melody (Schumann Resonance 7.83 Hz) Koolá’s sound machine is like no other white noise or pink noise machines available. The baby comforter with voice recording provides a multi-dimensional soothing approach for day or night, making it a favourite among FIFO families, travelling parents, and caregivers and children who attend preschool.
Q: What’s the best way to develop a sleep routine for newborn babies?
A: There are many factors that contribute to a successful sleep for infants. A well planned sleep routine that is consistent is a game changer for new parents. Unfortunately, infant sleep isn’t as easy as the saying goes: He’s sleeping like a baby! Key factors influence a baby’s sleep like: the child’s health, the baby’s feeding habits, daily sunlight exposure, daily stimulation levels and physical activities, the mother’s awareness of the infant’s sleep cues, the consistency of the events leading up to sleep (bedtime routine) the sleep environment and even the child’s feelings of safety and security influence the infants sleep. It’s quite complex and unfortunately most parents haven’t been educated on any of this before the baby arrives! I wrote an article about baby sleep and the newborn sleep routine here. I designed Koolá when my newborn would not sleep. Many new parents around the world now use our Koolá baby comforter as part of their nightly routine with their babies to build consistent sleep associations. Playing the soothing toy for baby and recorded parent voice before bedtime signals to the baby that sleep time is approaching. While every infant’s pattern differs, these gentle rituals can support a smoother sleep routine for newborns. Parents also love that our baby comforter can be used during travel, daycare naps, or pram outings to keep a familiar comfort close anywhere at anytime.
Q: Is the Koolá Doll a security blanket or comfort toy?
A: The Koolá Doll is both a baby comforter and security toy, designed to soothe through sound and soft touch. It acts like a lovey for babies, helping children transition between sleep cycles and fostering independence. Made from natural linen and Aussie wool felt, it’s a low-tox baby comforter, phthalate-free toy, and machine-washable. Certified to meet strict baby toy safety standards in Australia, NZ, EU, and USA, the koala toy is safe from newborn age when used per safe sleeping guidelines attaching to the baby crib using the crib clip hanging the baby sleep toy outside of the baby’s bed.
Q: What materials are used in the Koolá Doll and are they low-tox?
A: Parents increasingly search for low-tox baby comforters that are phthalate-free, BPA-free, and safe for newborn skin. The Koolá Doll is made from natural linen and Australian wool felt, with hypoallergenic phthalate-free stuffing. The chew-safe clip and teething ring are made from food-grade silicone, ensuring safety during teething stages. All components are independently tested to comply with global infant-toy safety standards, making it one of the few baby sleep toys certified in AU, NZ, EU and USA.
Q: How can a baby sleep toy support FIFO families and parents working away?
A: The Koolá Doll baby comfort toy was designed by an Australian mum for her child who would not go to sleep. She found when her baby heard her voice singing a lullaby, she was calmer and fell asleep better than other sleep music. Since Koola has been on the market parents from all walks of life have reported the baby comforter to help their infants and toddlers settle at night and feel comforted during times of distress. One really interesting group is those who are Fly in Fly Our Miners. Families separated by distance or shift work. With Sing-to-Sleep Technology™, FIFO parents can record their voice before leaving home, offering nightly comfort and familiarity to their child while they are gone. The voice record baby toy replays that soothing song from their voice all night long, helping children feel connected to mum or dad even when apart. It’s an ideal baby gift for FIFO parents, defence families, or any parent working away from home.
Q: Is the Koolá™ Doll suitable for kids with autism or anxiety?
A: While the Koolá Doll is not a therapeutic device, many parents of autistic or neurodivergent children report to us that the special soundtracks and mother’s lullaby create calm for their kids. Research also shows that for preemie babies playing the child a recording of the parent’s voice resulted in positive health and development outcomes. Heart rates dropped and infants showed calmer biometrics. The rhythmic frequencies and heartbeat sounds in the baby sound machine has also been reported by parents to support emotional regulation during transitions and bedtime routines. Its low-tox materials, absence of Wi-Fi or LED flashing, and tactile softness make it a popular sensory toy for babies and toddlers on the spectrum.
Q: What is the best pregnancy gift for an expecting mother?
A: The best gift to give any new parent aside from a healthy baby is the gift of sleep! Sleep for their baby and sleep for themselves! The Koolá Doll is a gift for pregnant mothers and new parents that will be more appreciated long term more than any other baby shower gift as it has been reported by new parents around the world to support their infants sleep routine. There is something special about a pregnant mum receiving a Koola before birthing their child as when the baby is in the womb science shows that the baby can hear the mothers voice and also remember songs sung! If the mother is aware of this strategy, they can create what Koola coined as a “Womb Song” where the mother sings to the fetus daily and when the baby is born that song is played as the baby’s soothing lullaby for sleep! It is a parent hack all pregnant mothers should be made aware of. So here at Koola we believe the best gift any expecting mother could receive is a Koola Doll! It’s a thoughtful and practical pregnancy gift or baby shower present, symbolising the bond between parent and child from the very beginning.
Q: What is the best comforter toy for daycare or preschool naps?
A: The Koolá Doll baby sleep toy is a unique baby sleep toy perfectly suited for daycare nap time or preschool rest routines. Teachers and carers love that it provides a consistent cue for sleep and comfort away from home using the parents voice recording lullaby. When toddlers and babies are at preschool they miss their parents. Koola helps to keep a part of their parents close even when they are away. Outside of daycare times parents often use it in during their toddler bedtime routine or as a travel sound machine for their child when they are on the go. The clip-on design is popular as a pram toy preventing Koola from getting lost when out shopping or in public, making it ideal for all situations.

Q: Is your baby comforter different to other baby
sleep toys?
A: The Koolá Doll stands apart for many reasons, firstly it’s a low tox toy – a natural safe linen plush koala toy for babies and it loved by kids past toddlerhood, kids of all ages are comforted by Koolá. Being phthalate free is unique for a baby toy today as most velvet and fluffy soft plush comforter toys on the market are drenched in chemicals to achieve those fabrics. Secondly, it’s designed around infant sleep. The founder of Koolá created the doll when her newborn would not sleep. She found research linked to why the mothers voice was so effective for baby’s sleeping and calmness. Koolá also is different because the sleep soundtracks are designed using special sound frequencies that align to sleep brainwaves. Koolá combines the emotional warmth of a lovey with the innovation of a portable sound machine. It’s not just a plush comforter baby toy, it’s neuroscience-inspired with the power of the mothers voice as the babies first lullaby. And with the additional sleep soundtracks featuring 528 Hz Solfeggio tones, delta wave frequencies, and gentle womb heartbeat audio, it creates a natural rhythm that supports calmness and routine. Unlike mass-produced security blanket toys and infant white noise machines, each Koolá comforter is carefully designed for connection, safety, and long-term use from newborns to toddlers and beyond. It is a product that can be handed down form siblings and through generations.
Q: What is the Schumann Resonance and why is it in the Koolá Doll soundtracks?
A: The Schumann Resonance (7.83 Hz) is often called the Earth’s natural heartbeat frequency. It’s the rhythmic pulse found in the Earth’s magnetic field. The Koolá Doll’s soothing sleep music integrates subtle 7.83 Hz tones throughout the womb heartbeat soundtrack. These natural sound frequencies are designed to gently mimic the calm rhythms of nature, which also just happen to be the same brainwave hertz as a human’s brain waves when they are in the Theta state, which is a pre sleep brainwave state. Customers report these soundtracks help their babies and children feel grounded and relaxed during rest.
Q: Can I record other sounds into the doll?
A: Yes you can literally record any sound you want directly into the plush toy koala. Parents love this feature because it makes the baby comforter completely personalised. Most parents record their own voice, baby lullabies, or favourite bedtime songs, while others use gentle sounds or music their child already knows. Some parents even record favourite TV songs or their toddlers favourite short stories, anything that feels familiar and soothing for their little one.
The linen doll functions as a baby comforter with voice recording, allowing your chosen sound to play continuously all night. There’s a volume up and down button so parents can adjust the sound levels to suit the children’s needs. It’s simple to use, with no signals from Wi-Fi, Bluetooth, or apps, making it a safe baby sleep toy for everyday use. Parents often choose it as a natural alternative to infant white noise machines or portable sound machines because it creates a familiar atmosphere without the irritating sounds of white noise.
Many customers share that their babies respond differently to hearing a parent’s voice in song over music. They often tell us Koola helps make bedtime feel calm and predictable for their babies and toddlers. Parents use the doll during naps, travel, or daycare, saying the familiar recordings help their baby be more relaxed when away from home.
We’ve also heard from parents who tell us their child with anxiety feels more at ease when they can play a comforting message or song through the Koala Toy. One mum told us she recorded her voice saying “Mummy loves you” and it helped her little one stay calm when starting daycare. Every family uses their baby comforter in a unique way, that’s the beauty of this simple yet useful design.
The doll’s all night playback feature loops continuously, so your recorded sound can play softly all through the night if desired. Parents often describe it as their preferred baby calming toy, sleep companion toy, or baby sleep music alternative — something that supports bedtime routines and offers comfort without overstimulation.
Whether you record a gentle lullaby, a loving message, or familiar music, this personalised baby comforter becomes more than a toy — it becomes part of your family’s bedtime tradition. Parents say it’s one of those baby sleep toys that grows with their child, offering comfort from newborn to toddler years and beyond.
