How many night wakes are normal at your baby’s age
Someone at baby group has a five-month-old who sleeps through. You have counted six wakes and you are trying to work out what you did wrong. Almost certainly nothing - but the numbers people quote at each other are the wrong numbers.

Infant sleep is described in averages and lived in ranges, and the gap between those two things causes an enormous amount of unnecessary worry. An average of two night wakes at eight months does not mean most eight-month-olds wake twice. It means some wake never and some wake six times, and the middle of that spread describes almost nobody in particular.
It is also worth knowing that “sleeping through the night” has a formal definition in much of the research - often a five-hour stretch, sometimes midnight to five - which is not what anybody means when they say it out loud. A baby who does one five-hour block and then wakes three times fits the definition and would not feel like it to you.
Rough ranges, held loosely
Newborn to three months. Waking every two to four hours around the clock is the design, not a problem. Feeds are needed at night and long stretches are not expected.
Three to six months. Anywhere from two to five wakes is common. A longer first stretch usually appears somewhere in here, and often disappears again around four months when sleep architecture changes.
Six to twelve months. One to three wakes is typical, and one or two night feeds remain common well into this range. Plenty of babies at this age still wake more, and are entirely well.
Twelve months and beyond. Nought to two is the usual spread. Waking continues to be normal through the second year, particularly around teeth, illness and separation anxiety.
When the number does tell you something
The count matters less than the shape. Six evenly spaced wakes across the night usually points somewhere different from one long first stretch followed by hourly waking after 3am, even though both are “a lot”. Evenly fragmented from the very first hour is worth taking seriously as a possible physical cause. Fine early, difficult later usually points at sleep pressure, hunger or the settling association.
A sudden change is more informative than any absolute number. A baby who was waking twice and is now waking six times has told you something happened - teeth, illness, a developmental leap, a schedule that no longer fits. A baby who has always woken four times has told you very little except that they wake four times.
The average night belongs to nobody. Compare your baby to last month, not to the baby at playgroup.
What to do with all this
Write down what actually happens for three nights before deciding anything. Times, not impressions - memory turns four wakes into “all night” and a bad first hour into a bad night. Three nights of real numbers is usually enough to see whether you have a pattern or a run of ordinary variation.
And then decide whether it needs changing at all. Plenty of families are woken twice a night, are getting enough sleep overall, and do not need to do anything about it. The number worth acting on is not the one that differs from the internet - it is the one that is grinding you down.
What actually changes the number
Three things move the count, and none of them is a technique. Age moves it, slowly and unevenly. The falling-asleep association moves it, because a baby who needs help to start sleeping needs help at every cycle boundary. And total sleep across twenty-four hours moves it, because a day with too much sleep in it produces a night with holes.
Almost nothing else does, which is why so many families cycle through methods without the count changing. If you are going to act on the number at all, act on the day and on how sleep begins, and give either of those a fortnight before deciding it did not work.
Comparing honestly
Two things distort every conversation about this. People round down - “she sleeps through” frequently means one wake that is dealt with quickly and forgotten by morning. And nobody volunteers the bad weeks, so the picture you assemble from other parents is made of their best fortnights.
The only useful comparison is to your own baby a month ago. That one is available, it is accurate if you wrote anything down, and it answers the question you actually have - which is not whether this is normal but whether it is getting better.
When to stop troubleshooting
Frequent waking together with snoring, mouth breathing, pauses in breathing, poor weight gain, feeding difficulty or a baby who seems unwell in the day is not a numbers question. Talk to your GP or health visitor. So is any abrupt increase in waking that lasts more than a couple of weeks with no obvious explanation.
