Okay, just last week my dd started grabbing objects and playing with her toys at 4 mons. Before this, she was on a very predictable schedule. I knew when she would be taking naps, etc... Now I have no clue. She fights sleep more and she has cut out a couple of her naps altogether. Is this normal due to her new found love of toys? She seems so tired at night now and is going to sleep so early b/c she has cut out these naps. Will she eventually get back on track with her naps? Has anyone else experienced this and does it happen with every milestone they reach?
