Am starting to lose my mind a bit.
He's also taken to getting up for the day at 5am most days.
After a brief period of improvement his sleep has got worse since moving him into his big sister's room. We have also been on holiday where he was a pain to get to sleep every night, lots of fighting sleep.
Routine used to be, roughly: wake at 7ish, BF, breakfast etc, first nap about 3hrs 15 later, often first nap was 1.5 hrs. BF. Then lunch, then second nap about 3.5 hrs after the first nap and usually 45 mins/hr. BF. Sometimes he'll have a short first nap and long second nap instead. Dinner at 6ish, bath, bed. He will rarely sleep any earlier than 8pm.
At his best his sleep is 8pm-midnight (feed), feed at 3am ish, up at 6.30/7. This happens very rarely now.
He used to be good at settling himself but now am feeding to sleep and putting him in his cot. He's waking every 90 mins from 8pm for most of the night. If my partner tries to settle him he screams until I come up with my magic boobies.
Other factors - very big baby, very mobile (up and cruising furniture, fast crawling). Lots of change recently - holiday, then I did a week's work so his dad was looking after him every day (up from 2 days/week). He eats very well.
Can anyone suggest anything? Is he not sleeping enough in the day?? On the worst days recently we've put him back to 3 naps as he's knackered by 8.30am, but it's not improved the night sleep.
