This has been a mystery since she was 2 months old (She is now 7 mos). Every once in a while she would fell asleep by herself in crib (with a few cries or shu-pat) but every time she would wake up at the 45 min mark vs if she fell asleep in my arms she will sleep for at least 1 hour. Why?
Yesterday when I let her fell asleep in my arms for nap:
E 7:00
E 8:00 solid
S 9:50-11:30
E 11:30
E 1:20 snack and some sip of water
S 2:15-3:10
E 4:00
E 5:30 solid
E 6:30
S 6:45
NW 9:40 (Seems wide awake, plus she didn't eat much throughout the day, so I nursed her back to sleep)
NW 3:15 (pupd 3)
NW 3:50 (pupd 1)
Today:
E 6:00 (back to sleep after nursing)
WU 7:15
E 8:30 (bf)
S 10:05 (rocked to eyes closed, eyes were open when I put her down to crib. Fussed a bit and fell asleep by herself)-10:47
E 11:00
