I think my 15 mos old is trying to transition to 1 nap, slowly, but surely. We were at 1 nap for a month until we posted on here about NW's for 1-2 hours at a time. We returned to 2 naps and magic! DS is now sleeping 10 hours at night (no matter what time we put down it's 10 hours only), waking around 6/7am, awake for 3.5-4 hours, nap at 9:30/10am for 1.5 hrs, awake for 3-4 hrs, nap at 3:30/4pm 1-1.5 hours, awake 3 hours, bed at 8. I try not to let him sleep past 5pm so he's not up late. Generally he wakes up at 6am, but sometimes it's 7am. When that happens, obviously our day moves an hour back for everything. This is a little difficult when I am trying to transition from 2-1 by 15 min increments. So my question is do I stick to a time schedule (ie he goes to nap at 10am no matter what) or do I stick to a total time schedule (ie he goes to nap 4 hours after he wakes up)? Right now I am going with length of A time, unless he's super tired for some reason, and pushing A time farther by 15 mins every 3rd day, decreasing S time in pm nap and decreasing A time before bed. Does this sound right? Thanks!
