Before anything else: I'm a sleep consultant, not a pediatrician. For any feeding advice, please speak to your healthcare professional. What I'm sharing below is a guide, not a medical opinion, so if you have any concern at all about weight gain or your supply, that conversation belongs with your doctor rather than with me.

With that said — this is one of the most common questions I get, and it's one I got wrong myself.

What it looked like for me

With my second daughter, I constantly questioned my milk supply. I always felt like I never had quite enough. So when she woke in the night, I assumed she was hungry, every single time, and I fed her.

Hindsight is a wonderful thing. Looking back, I'm pretty sure most of those wakes were habit rather than hunger.

I'm telling you that because the fear underneath this whole question is usually not really about sleep. It's a mother wondering whether her baby is getting enough. I've been there, and I'm sharing my experience because I only realized it after the fact.

The four signs it's genuine hunger

This is for babies who are past the newborn stage. Newborns do need to feed every two to three hours, so the below information isn't applicable to them. But for babies over 3+ months, here are signs your little one might be waking up from genuine hunger:

1. Your baby can fall asleep independently — and after the feed, they can go back to sleep on their own.
2. You get a good stretch afterwards. Three to four hours is a reasonable guide.
3. It feels like a full feed. They don't fall asleep partway through it, and when you put them down they settle themselves.
4. They only need one or two feeds a night, until they're well established on solids.

There's also a timing tell. A genuine hunger feed usually comes in the early hours of the morning, after they've already given you a decent stretch of sleep in the first half of the night.

The four signs it's habit

1. After the feed, they can't fall asleep on their own. They need a lot more comforting to get back down.
2. They want to feed frequently — every one to two hours.
3. They want to fall back to sleep immediately. They take a few sucks rather than a full feed, and they cry when you put them down because they want to keep sucking.
4. They need many feeds through the night, and they have to be asleep when they go back down.

The same four questions, side by side

It's easier to see when you put them next to each other. These aren't two lists — they're the same four questions, answered two different ways.

Run those four questions at 2am and you'll have your answer.

The sign that fools almost everybody

She settled after the feed, so she must have been hungry.

I understand why that feels like proof. It isn't, and this is the thing I'd most like you to take away.

A feed does two jobs. It fills them up, and it soothes them. Sucking is calming quite separately from the milk. So a baby who takes a few sucks and drifts off hasn't necessarily eaten — they've been settled. The feed worked as a sleep tool rather than as food, which is exactly what habit sign three describes.

Settling afterwards tells you the feed helped. It doesn't tell you why.

If you're worried about underfeeding

This is the fear that keeps most parents feeding.

If your baby is genuinely hungry, they'll take a proper feed and then give you a decent stretch afterwards — three to four hours is a good guide. A few sucks and awake again ninety minutes later is not a baby who needed calories.

And if you're ever worried about weight gain or your supply, please speak with your pediatrician. Any feeding advice is deemed medical advice and must be discussed with a healthcare professional who can assess your baby based on their weight and development.

What you might have just worked out about yourself

Read back over the four signs of hunger and notice what most of them are actually measuring.

Sign one is whether your baby can fall asleep independently. Sign two measures whether that worked — whether the long stretch afterwards actually happened. Sign three is whether they stay awake through a feed and settle themselves after it. Only sign four is really about feeding at all.

So a test for hunger turns out to be mostly a test of how your baby gets to sleep. That's not an accident — for many babies, whatever gets them to sleep at bedtime is the same thing they'll need to start every new sleep cycle after that. If the feed is how they get to sleep, they'll often ask for the feed every time they come to the end of a cycle, whether or not they're hungry.

Of course not every baby, though (because they're all different!). Plenty of babies feed to sleep and still only wake once or twice, and if that's working for your family then there's nothing you need to change.

But if you're up four, five, six times a night and every one of them needs a feed, you've probably just diagnosed it.

Where to go from here

If that sounds like your nights, the piece that's missing isn't feeding advice. It's teaching your baby to fall asleep without needing you to do it for them — and once that's in place, the night feeds that were habit tend to fall away on their own.

My 5-18 Months Sleep Program takes you through it step by step: the day structure they need at their age (to put them down at the right time), and responsive settling based on your baby's temperament. It's 100 minutes of short videos, designed specifically for exhausted parents with zero attention span (I see you!).

If your baby is still waking 45 minutes after bedtime as well, it's caused by something completely different.

Common questions

At what age do babies stop needing night feeds?

There's no single age, and it depends on your baby and your pediatrician's assessment. As a general guide, most babies need only one or two feeds a night until they're well established on solids (somewhere between 8-10 months).

My baby is a newborn and feeds constantly. Is that a habit?

No. Newborns genuinely need to feed every two to three hours, and none of the signs above apply at that stage.

Should I just stop night feeds and see what happens?

Please don't do it that way, and please talk to your pediatrician first. Dropping feeds works when your baby can fall asleep without them — otherwise you've removed the tool and left the problem.

She takes a full feed every single time. Does that mean she's hungry?

It's a good sign that she is. Check it against the other three signs, especially the length of the stretch afterwards.
