How much Should My Baby Sleep ?
A lot. A truly staggering, almost offensive amount, and I say that as someone who hasn't slept properly since the second trimester. We're talking 14 to 17 hours a day. I'll take a look at NHS sleep guidelines for babies after I've read this post if I need more information..
Why Does My Baby Sleep All Day ?
Because they are a baby. But I know, I need the science to actually believe it. So here it is:
1. Their Brain Is Basically Building Itself While my tiny human is snoozing away looking like the world's most content little potato, their brain is absolutely going off. Neural connections are forming at a rate that will never happen again for the rest of their life. Sleep is when the magic happens, research from Harvard Medical School shows that sleep plays a critical role in memory consolidation and brain development.
My baby is running a full operating system update every single nap. I will not disturb them. I will not even breathe too loudly.
2. Growing Is Exhausting Work
Babies double their birth weight in the first five months. Let me just sit with that for a second. If I doubled my size in five months, I would need a nap. Several, actually. An extensive, uninterrupted, do-not-knock-on-my-door nap.
My baby isn't being lazy. My baby is doing the hardest physical work of their entire life so far. And they're doing it brilliantly.
3. They Have No Idea What Day It Is (And Honestly, Same)
My baby recently came from a place with no light, no schedule, and a constant muffled soundtrack of my internal organs. They have absolutely no concept of Tuesday. Their circadian rhythm — the internal body clock that tells us when to be awake — takes a few months to fully develop. Until then, the schedule is: sleep, eat, stare at the ceiling fan in quiet wonder, sleep again.
This is not me failing at routine. This is just biology doing its thing.
Is It Normal For My Baby To Sleep After Every Feed ?
Yes. One hundred percent yes. I'm going to write it on a Post-it and stick it to the wall.
My baby falls asleep mid-feed, finishes a feed, and then immediately drifts off like they've just had a full Sunday roast. Feeding is genuinely hard work for a tiny person. Their little tummy fills up fast, and the combination of warmth, closeness, and a full belly is basically the ultimate sleep cocktail. I'd be asleep too.
The La Leche League , a brilliant resource for breastfeeding support — notes that it's completely typical for newborns to doze during feeds, and that it doesn't necessarily mean they're not getting enough milk.
If my baby is:
Producing plenty of wet and dirty nappies ✅
Gaining weight steadily ✅
Waking up for feeds, even if only every few hours ✅
Then we are winning. All of us. Except me in the sleep department. But they are winning.
What is My Baby Actually Doing When They Sleep ?
I'm glad I asked. Here is the full itinerary of a typical baby nap, so I can stop feeling like I need to be doing more:
Minutes 1–5: Light sleep. I will not move them. I will not put them down. I will not so much as sneeze.
Minutes 5–20: Deeper sleep begins. The twitching starts. Completely normal. They are processing the seventeen things they discovered today — that light exists, that my face exists, that the ceiling is fascinating.
Minutes 20–45: Deep sleep. Brain development happening. Growth hormones releasing. An absolute scientific marvel is taking place inside a sleep sack.
Minutes 45+: Cycling back into lighter sleep. This is the famous 45-minute nap. I have been warned about this. I am prepared. (I am not prepared.)
While all of this is happening, their body is:
Releasing growth hormone — yes, most of it is released during sleep
Repairing cells and tissue
Filing away everything they experienced today
Looking unfairly adorable while doing all of it
When Should I Actually Worry ?
Okay. Real talk. Because I need to know when it's fine to exhale, and when I should actually pick up the phone.
Most of the time, my baby sleeping a lot is completely, boringly normal.
But I should check in with my GP or health visitor if my baby:
Is impossible to rouse for feeds and hasn't eaten in more than 4 hours as a newborn
Has signs of jaundice — yellowing skin or eyes — and seems unusually hard to wake
Has a fever alongside extra sleepiness
Isn't gaining weight or has fewer wet nappies than expected
Seems limp, pale, or unresponsive
My health visitor is genuinely there for this. Ringing them is not dramatic. Ringing them is not wasting anyone's time. Ringing them is exactly what a good mum does.
The NHS 111 service is also there 24/7 if I'm ever unsure and it's 3am. Which, statistically, it probably is.
