Need help for sleep

Every baby is different unfortunately.
Mine is 3m and sleeps 7/7:30 until 6-7 (sometimes later than 7) , but includes changing, feeding and then he just goes back to sleep. We didn't do anything.. he just likes to sleep.

We are careful with the sleep during the day tho. We are usually capping his total sleep at 4h

Put them to bed later. The average night is 10.5 hours long.

A baby only has a maximum sleep need in 24 hours. If they’re having tonnes of day sleep naturally there’ll sleep less at night

Put to bed later

How early is the first nap? If the morning nap is too early they get up earlier to make sure they are tired enough for it

My little girl is 8 months old, I went through a long 5am get up phase, I’ve just managed to get her to go down 7pm-7am, she has 60-90mins at 9am and then 60mins at 2.30pm, then we’re in her bedroom for 6.30 and she’ll be asleep for 7.
Milk wise I make her 240ml (8oz) I’ll offer it at 7.30am, 11am, 3.30am and then her final milk before bed I make 270ml(9oz). If she doesn’t drink the whole bottle when I offer it, I will give her the rest before her next sleep.
Food wise I’ve just started giving her a 3rd ‘meal’ so she’s now having breakfast lunch and tea which I do around 8.15am, 12.30pm and then 5pm.

Food and milk isn’t rigid and strict, but tryi bf to keep them 2 naps stable and at the same time is what seems to have helped me, I found I was getting it right in the week but then when my partner came home they’d go out the window, and I’d push the nap 30 mins to fit in with us going out. The past few weeks I’ve stopped this and will get her to sleep no matter what x

I stopped that by doing bedtime later. We do absolutely not before 8 but you’re in that bed by 9 at the latest because I have to breathe before I go to sleep. Now up at 7ish. I know this doesn’t work for everyone but it did for us
