DD is 4 months, is beginning to sleep really well at night - i.e 7 to 7 with 1 or 2 wakeups but still can't stay awake from more than an hour tops during the day. She'll only nap for 40 mins which means it feels like I spend the whole day putting her down for naps - sometimes 5 a day. I'd thought that by this point she'd be able to extend her awake time longer but the most she can ever stay awake without getting grizzly and cranky is 1.5 hours and this is on a GOOD day. A lot of time its only 45 mins! Does anyone else have similar babies?
