Meg, I agree about the slightly earlier nap. I think the A time in the morning is fairly long. I was able to push Isabella to 6 hrs at 2 & then 6.5hrs soon after that but he might not be able to handle 6.5hrs
yet so try 5.5hrs so that he falls asleep by the 6hr mark. I might be reading it wrong but wake up time is 6.30-7am & nap is 1-1.30pm... so from wake up (6.30-1pm) thats 6.5hrs. Also are you sure he wakes at 6.30-7am (stupid question really but unless I check the video camera I am never sure what time my girls wake or go to sleep. Isabella started calling out of me a while ago but at 2 I am pretty sure she used to just roll around quietly until I come & get her)
also this drop in sleep happened so abruptly and i dont know what caused it. He went from sleeping 10.5-11h nights and 2+ hour naps to 10.5h nights and 45-1hour naps.
Funny you made this comment... I was just posting very same thing in Kelly's post (about Zander). Isabella's sleep changed dramatically at around age 2. She went from 11.5/11hrs at night down to 10.5 & her nap reduced to 1.5hrs. It was so sudden...
Do you think he could be teething at all? Have you tried to leave him in the room if he wakes before 1hr to allow him to fall asleep again? I used to go in & tell her nap time is not over & to go back to sleep. This worked 99% of the time (sort of wi/wo). I never took her out of the cot at 45mins mins at that age. So you might want to give that a go
Also the amount it takes to windown can be as long as 30-40 (well always been the case here) but 1hr is either too stimulated/overtired or not tired enough. Considering he looks & acts tired during the day & wakes up screaming from nap, I would say its overtired. What activities do you do before nap time & bedtime? Does he watch tv at all in the evening? How long is your wind down - if its longer than 40mins thats more like an activity than a wind down so might not be helping him relax...
At that age, Isabella's day was something like this:
6ish - wake
12.30 - 2 nap (again she needed a longer A time or she would wake at 5.30am)
7pm - bed (asleep by 7.30pm)
