What did your baby acomplish this week?

Not only do I want to know what your child acomplished, but I would also like to know when your child was starting to focus on other things besides you. My daughter was 15 weeks old yesterday, and this week she became interested in holding things. She played with toys on her changing table for atleast a half hour before bath time the other night. And last night in her bath she was looking for her nemo and dori toy and picked it up numerous times!! im soo excited. when did your baby start this behavior? Thanks!
