Thanks everyone! Yes he will be 3 end of June! We do up for bt at 7 bath pjs songs and usually asleep brown 730-8 but he always went to sleep on his own no problem. Now I can't leave the room without him getting upset and crying. So many changes going to be happening with a baby coming early July and summer camp mud June and preschool in September. I guess it could be developmental. Doesn't seem to matter how much physical and/or mental activity he had in a day, like it used to.
