Or are you supposed to help them self settle in some way? I don't remember this from my first baby because she was a terrible sleeper from birth anyway.
DS is 4 months this week and has always been a really good sleeper. He has never had awake time in the night, has just fed back to sleep after night feeds and since about 6 weeks has just had the one feed in a 6.30ish-5.30ish sleep.
This last week I've struggled to get him down, usually have 3 or 4 'false starts' to the night and he cannot be left to self settle, if he isn't in deep sleep and floppy when I put him down he is wide awake and shouting when he touches the mattress. He also properly wakes up for the night feed and is then awake and wanting to play for about 1.5-2 hours. He has also been starting the day at 4.30. last night he fed every hour of the night.
It's hard because I also have a 2 year old who doesn't reliably nap so can't ever catch up in the day. I'm so so tired this morning!
Hes a big baby, 85th percentile for height and weight and my mum has said start him on solids but it seems way too early!
