Do you think it might be at all related to your pregnancy? DS started sleeping differently when i was about 8 months pregnant..
I never considered my being pregnany something that might affect her, she is very observant and I swear she is sort of understanding what is happening. She has started playing excessive babies with her new doll in the last two weeks, rather cute, and is literally baby obsessed, on tv, in books, at the shops, at daycare.

I am going tomorrow to have a look at the seahorse ones, her new room is going to be underwater theme, or we are going to ikea in a few weeks and I did like some of their lights last time we were there. I guess for now we will see how she goes.
