thanks for reply,
he's been short napping since he's 5 months, at least... :/
he hasn't been on any schedule - I was just putting him sleep when I noticed he's getting tired (two naps a day - morning usually between 10-11am and afternoon 3-4pm - both 45 mins w/BF before).
now I'm using PD to put him sleep - again 2 naps for 45 mins each and doesn't go back to sleep after doing PD for 45 mins after awake... :/).
today I put him only for one nap - at 12 (he woke up again after 45 mins and wouldn't go back to sleep w/PD).
I put him sleep for night at 6:20pm - fall asleep right away but since now (8:20pm) woke up twice - at 7pm and 8pm. he falls asleep w/ my hand on his belly now - I think it became a prop now and I don't know how to change it because he cries and won't sleep w/o it... :/
