Just that really. He wakes approx 7.30. Used to always sleep for a nap from 12.30 till 2.30 or 3. Now he won't sleep when I put him down, asks for a second bottle and won't sleep till about 1.30 or 2. Problem is he will sleep till 4 if I let him and he won't sleep at bedtime then he's up till 9.30! Any advice please? I've tried days with no nap and he's been fine. Bed at 7 and fast asleep at 7.30. But so far all I'm reading is that they still need naps at this age for brain development? He's always full of energy in the daytime, but will nap eventually so he must be tired? Gosh I hate trying to figure out infant sleep 😅😅
