Why Does My Baby Only Sleep in My Arms?
By Chloe Roche, Certified Infant & Child Sleep Consultant
Does your baby settle peacefully in your arms but wake as soon as you put them down? You are not alone. Many parents find that their baby sleeps more easily when held and struggles to stay asleep during a cot transfer.
It can be exhausting when your baby seems to need your arms for every nap or nighttime sleep. You might wonder whether you are doing something wrong or whether your baby will ever sleep comfortably in their own space.
The good news is that this experience does not automatically mean you have created a bad habit. Young babies are still developing their sleep patterns and settling skills, and many factors can influence how easily they settle and stay asleep.
Let's explore why your baby might sleep better in your arms and how you can gently support them to sleep in their cot or bassinet.
1. Your baby is still adjusting to life outside the womb
Your baby has moved from a warm, contained environment into a world of new sounds, lights, temperatures and sensations.
Being held offers warmth, touch, your voice, your smell and sometimes gentle movement. These sensations may help a young baby feel settled and secure.
This is one possible contributor, rather than a complete explanation for every baby's sleep. Each baby is different, and their age, development and individual sleep patterns can influence how they respond to being put down.
2. Your baby may still need help to settle
Young babies are still developing their ability to move between alertness, distress and sleep. They often rely on caregivers to help them settle when they are tired, overwhelmed or uncomfortable.
This shared process is often called co-regulation. Your touch, voice, movement and responsive presence may help your baby become calmer. These abilities develop gradually through experience and maturation, not according to a fixed timeline.
Research on parent-infant co-regulation explores how caregivers and babies influence one another through interactions, including touch. However, this research is not a specific sleep intervention and does not explain every baby's preference for being held. (Montirosso & McGlone, 2020)
Responding to your baby is not spoiling them. You can offer comfort while gradually giving them opportunities to become familiar with their own sleep space.
3. Your baby may wake when you put them down
You may have spent time settling your baby in your arms, only for them to wake shortly after their body touches the mattress.
A change in position, the loss of your warmth or movement, or the transition from being held to lying on a mattress may contribute to waking. Sometimes, your baby may simply not be ready to remain asleep through the transition.
A small 2022 exploratory study examined how the timing and process of transferring sleeping infants affected whether they stayed asleep. The findings suggest that the transfer process may influence sleep, but the study is exploratory and does not establish one method that works for every baby. (2022 infant transfer study)
If you would like to experiment, wait until your baby appears settled, lower them slowly while supporting their body, and place them on their back in the cot or bassinet. Some parents find that keeping a gentle hand on their baby briefly after the transfer helps make the change feel less abrupt.
There is no single transfer method or waiting time that works for every baby. You do not need to keep repeating an approach that is making you or your baby more distressed.
4. Infant sleep changes as your baby grows
Newborn sleep can look very different from the sleep of an older baby. Sleep patterns develop over time, and babies gradually experience changes in their sleep organisation and circadian rhythms, which help regulate the body's sleep-wake cycle.
These changes do not happen overnight, and there is no exact age when every baby will begin sleeping for longer stretches or settling easily in a cot.
Research has explored how infant sleep develops and how sleep-wake rhythms change during early life. However, these studies do not prove why a particular baby sleeps more readily in their parent's arms. (Infant sleep development review) (Neonatal sleep and circadian rhythms)
Your baby's age, feeding needs, health, environment, and individual temperament can all be relevant when considering their sleep patterns and settling cues.
5. Is contact napping a problem?
Not necessarily.
If your baby sleeps well in your arms, it does not automatically mean you have created a problem or that you must stop contact naps immediately.
Contact naps can be a practical way to help your baby rest, particularly when they are very young. At the same time, being responsible for every nap can be physically and emotionally demanding. It is reasonable to want your baby to become more comfortable sleeping in their own space, too.
You can respond to your baby's need for closeness while exploring other settling options when they suit your family. You do not have to choose between being responsive and helping your baby become familiar with their cot or bassinet.
The important thing is to consider your baby's developmental stage, your family's circumstances, and safe sleep practices.
If we are working together to achieve independent sleep when your family is ready and your baby is under 8 months of age, there is usually a need for a brief afternoon nap which I will always recommend be assisted! This is where we get those beautiful contact naps in. Also, don’t fret, you will have years of your child and baby falling asleep on you as you travel, navigate illnesses, and lean into the very normal ebbs and flows of paediatric sleep (sometimes, even the best-settling baby or child, just needs that contact nap!)
6. How can you gently support your baby to sleep in their cot or bassinet?
You do not need to change every sleep at once. Small, manageable steps may help you understand what works for your baby.
Start with one cot or bassinet attempt
Choose a sleep when you have the time and energy to try a transfer without feeling rushed. You might begin with one daytime nap or another sleep that feels manageable.
If the attempt does not work, you can pause and try again another time. One difficult transfer does not mean your baby cannot learn to sleep in their own space.
Look for early tired signs
Notice changes in your baby's behaviour, such as becoming quieter, looking away, yawning or losing interest in their surroundings. These cues can vary with age and from baby to baby.
Rather than relying on a strict schedule alone, consider your baby's age, usual sleep patterns and settling cues together.
Keep the transition calm
A familiar settling routine may help your baby recognise that sleep is approaching. Depending on their age and preferences, this could include lowering the lights, speaking softly, cuddling or using gentle movement.
You can continue offering comfort if your baby becomes unsettled. The aim is not to leave your baby distressed but to find an approach that supports both their needs and yours.
Give yourself permission to adapt
Some days, your baby may settle more easily than on others. Feeding needs, development, illness, discomfort, and changes in routine can all affect sleep.
You are allowed to adjust your approach. If repeated transfers are becoming stressful, take a break where possible and seek support rather than feeling that you must keep trying until it works.
7. Keep safe sleep at the centre of every sleep
Although it is understandable to want your baby close, safety matters whenever your baby sleeps.
If you think you might fall asleep, place your baby on their back in their own safe sleep space before you fall asleep. Falling asleep with a baby on a sofa, armchair, or recliner is extremely dangerous. Falling asleep with your baby on your chest while lying down or semi-reclined is also unsafe.
For every sleep, place your baby on their back in their own safe sleep space. Use a safe cot or bassinet with a firm, flat, well-fitting mattress. Keep their head and face uncovered and remove pillows, cot bumpers, doonas, soft toys and loose or bulky bedding. Keep your baby smoke- and vape-free before and after birth.
Red Nose recommends keeping your baby's own safe sleep space in the parent or caregiver's room for at least the first six months.
Read the full guidance from Red Nose: Six safe sleep recommendations and Red Nose: Home couches and co-sleeping.
If your baby seems persistently uncomfortable, has feeding difficulties or is not gaining weight as expected, speak with your GP or child health nurse. If your baby has difficulty breathing, turns blue, becomes floppy or unresponsive, or is unusually difficult to wake, seek urgent medical help or call 000.
Finding an approach that works for your family
If your baby only seems to sleep in your arms, it does not mean you have done anything wrong. Young babies are still developing, and settling independently can take time.
You can offer comfort and connection while gently exploring ways to help your baby sleep in their own safe space. There is no need to compare your baby's sleep with another child's or expect progress to follow a perfect timeline.
If you are feeling exhausted, unsure what is appropriate for your baby's age, or struggling to find an approach that works for your family, personalised support can help you understand your child's sleep and explore practical next steps.
