Curious what time of day your 2 year old is napping and going to bed at night? I have recently moved ds's nap from 12 to 1pm (he's now 23 months) because he suddenly stopped napping well. Was always napping a good 2 hours but then most days only 1 - 1 1/2 hours and I thought later nap would help. So far - after 1 week -- still short nap. He'll go to bed by 7:15-7:30pm but many mornings wakes early (before 6 am) and seems very cranky and unrested all morning (starting from as early as 8am). What has happened?
