Sam has been smiling for a little while now. I think her official first smiles were in Michigan when she was 3-4 weeks old. The picture above is one I caught on camera yesterday. She especially likes it when you praise her, then you get a giggle and a smile. Needless to say, she is going to think she is amazing pretty soon with all the praise she is getting.
She also loves the lights and music on her bouncy seat. She will sit in there for a long time and just giggle. We've learned to use this during shower time. I am trying to get a video of it, but haven't had any luck yet. I think it's pretty cute. I might be biased though.
