My 5-month-old won't sleep unless fed

Feeding to sleep at 5 months is common and not harmful. Here's why it often gets worse around 4 months, whether your baby still needs night feeds, and gentle ways to change it if it's wearing you out.

Your 5-month-old drifts off at the breast or on a bottle and nowhere else, for naps, bedtime and every 2 a.m. wake-up. It often ramped up around 4 months, and now you're awake every hour or two.

Lots of babies feed to sleep, and it does them no harm. Change it only once it stops working for you, and do it gently.

Why does my baby only fall asleep while feeding?

Sucking, warmth and a full tummy make babies drowsy, so feeding is the quickest route to sleep. When they stir, they look for whatever helped them drift off. These cues, like feeding, rocking or a pacifier (dummy), are called sleep associations.

From around 4 months, sleep runs in cycles of about 30 to 50 minutes, with light sleep or a short waking between each one. A baby who nodded off on the breast or bottle will often want that feed every time they surface. This is the so-called 4-month sleep regression, a normal sign that your baby's sleep is maturing.

Is feeding to sleep a bad habit?

No. If nursing or rocking to sleep suits you both, carry on. You can't spoil a baby by comforting them, and plenty drop the feed on their own later.

Change it when the wake-ups are too much, or nobody else can settle your baby.

Is my baby still hungry at night?

Often, yes. Some babies manage 5 to 8 hours by now, but many still wake to feed. Advice on dropping night feeds varies: in the UK, some babies no longer need them from about 6 months, and in Ireland, once solids are fully established, usually at 6 to 9 months. Check with your doctor before cutting any, especially if your baby has been slow to put on weight.

Hourly waking is rarely all hunger. If your baby takes a few sucks and is out cold, that feed is mostly a way back to sleep. A distracted baby takes short daytime feeds, so offer daytime feeds somewhere quiet and dim.

How to gently stop feeding your baby to sleep

Start with bedtime, and give each change a few days before you add the next.

Feed earlier in the routine. Every night or two, move the feed about 10 minutes earlier, so a book or a song comes last.
End the feed as sucking slows. When the sucking turns fluttery, gently break the latch or ease the bottle out, then rock or pat the rest of the way. Stop a little sooner each time.
Lay your baby down drowsy but awake. Put them on their back in the crib while calm and heavy-eyed. Shush or pat them, lift them for a cuddle if they cry, and don't leave until they've dropped off.
Hand over to someone else. Your partner can take the end of bedtime or a night waking. Many babies settle more easily when milk isn't an option.

Expect a few fussy nights, and pause if your baby gets sick. Sleep training does little before 6 months, so small, gentle steps make more sense now. Dream feeds and cereal in the bottle haven't been shown to stretch sleep either. Never put your baby to bed with a bottle.

Keeping your baby safe when they fall asleep feeding

Once your baby is asleep, lay them on their back in their own crib or bassinet, on a firm, flat mattress with just a fitted sheet. Keep the crib in your room for at least the first 6 months.

The main danger is you dozing off too. Both the AAP and the NHS say a sofa or armchair is no place to fall asleep with your baby. If you might doze off while feeding, feed in bed with pillows and loose bedding cleared away, and move your baby back to the crib the moment you wake.

What other parents say

For many, it started at 4 or 5 months, along with plenty of guilt about "creating a bad habit." An earlier feed, a partner taking bedtime or night wake-ups, and unlatching a little sooner each night helped most. It took a few days to two weeks, with some tears, and a cold or new teeth could set it back. Plenty changed nothing, and their babies outgrew it anyway.

When to get help

Feeding to sleep is not an emergency in itself. Call your pediatrician or family doctor (UK: health visitor, GP or NHS 111; Australia: child and family health nurse or healthdirect 1800 022 222; Canada: 811 in most provinces) if:

your baby is gaining weight slowly, has fewer wet diapers (nappies) or turns down feeds
you hear loud snoring, gasping or pauses in breathing while your baby sleeps
the night waking started along with a fever or other sign of illness, or your baby seems sore
you're worn out or low, or afraid you'll fall asleep with your baby in your arms

If tiredness is turning into anger, read feeling angry when your baby won't stop crying.

The bottom line

Feeding to sleep is fine at this age, as long as your baby ends up on their back in their own crib. If the nights are grinding you down, an earlier feed and other small changes can loosen the habit with little crying.

FAQ

Is this the 4-month sleep regression?

In part. Sleep breaks into short cycles from about 4 months, and a baby used to feeding to sleep tends to ask for milk after each brief waking. That's normal development, and you didn't cause it.

Is it OK to let a 5-month-old cry it out?

There's no need. In studies of babies younger than 6 months, sleep training made little or no lasting difference. Slow changes with you beside the crib suit this age better.

Will solid food make my baby sleep longer?

Not by much. In a trial, babies given rice cereal in a bedtime bottle were no more likely to sleep through the night. Start solids at about 6 months when your baby is ready, never as a sleep fix.
