Sound familiar?

Sometimes it feels as though babies have a built-in alarm that goes off the moment a parent steps away.

Why does this happen? And can you help your baby become more comfortable sleeping in their own cot?

Why does your baby wake up when you put them down?

For a newborn, being held means warmth, familiar sounds and gentle movement. They can feel your touch, hear your voice and sense your body nearby.

When you put them down, several of those sensations change at once.

Newborns also have a startle response called the Moro reflex. A sudden change in position can make a baby's arms jerk outwards and interrupt their sleep.

The need for close contact is especially common during the first few months, when sleep patterns are still developing.

And no, it doesn't mean you've “spoiled” your baby by holding them too much. Wanting closeness is a normal part of early development, not a bad habit.

Of course, frequent waking can have other explanations too, including hunger, discomfort, temperature or overtiredness.

Five gentle ways to help your baby settle in their cot

1. Give them a little time before putting them down.

A baby who has just closed their eyes may still be easily disturbed. Try waiting until their breathing seems calmer and their body has relaxed.

2. Make the transfer gradual.

Support your baby's head and body as you gently lower them onto their back. You can briefly rest a hand on their chest without applying pressure, helping the change feel less abrupt.

3. Create a simple bedtime routine.

Dim lighting, a quiet voice, feeding when needed and a familiar sequence of activities can make bedtime more predictable.

4. Try putting your baby down when they're sleepy but still awake.

Some babies gradually become more comfortable falling asleep in their cot. If your baby becomes upset, comfort them. Every bedtime doesn't need to become a training session.

5. Start with one daytime nap.

You don't have to change every nap at once. Try using the cot for one nap when your baby seems relatively calm.

And remember: something that works today might not work tomorrow. Infant sleep changes constantly.

Is it safe for a baby to sleep in your arms?

Holding a sleeping baby is possible when the adult is fully awake and supporting them securely.

But falling asleep with a baby on a sofa or armchair is dangerous. A baby can slip into a position that makes breathing difficult or become trapped against cushions.

For routine sleep, the safest option is a separate cot or bassinet with a firm, flat mattress.

Always place your baby on their back. Keep pillows, soft toys, cot bumpers and loose blankets out of the sleeping space.

For at least the first six months, the baby's cot should be in the same room as the parents.

Avoid pillows carrying a parent's scent, sleep positioners or soft baby nests, even if they're advertised as products that help babies sleep longer.

What if you're completely exhausted?

This part of the conversation often gets overlooked.

When your baby sleeps only while being held, finding time to eat, shower or simply rest can become surprisingly difficult.

You don't need to do everything yourself.

If possible, agree on specific responsibilities with your partner. Who settles the baby? Who prepares dinner? Who takes care of the household chores?

If you're struggling to stay awake, put your baby down in a safe sleeping space and ask for help.

Preferring to sleep in someone's arms is not usually a sign of illness. However, speak to a healthcare professional if your baby feeds poorly, isn't gaining enough weight, seems to be in pain or develops other concerning symptoms.

A temperature of 38°C or higher in a baby younger than three months needs urgent medical assessment.

Do you actually need to stop holding your baby to sleep?

Not necessarily.

If contact naps work for your baby and your family, there's no reason to change everything immediately.

And if you're exhausted and want to gradually introduce more sleep in the cot, that's reasonable too.

The goal isn't to achieve perfect sleep at any cost. Your baby might settle independently today and need extra cuddles tomorrow.

That doesn't mean you're doing anything wrong.
