1st laugh?

Today Wes was playing with Ellie. Getting in her face, making silly sounds and waving her arm back and forth. I was telling him to stop because I was worried he was getting carried away and would hurt her. Then I heard her make a loud squeaking sound and started to say, "See Wes, now you hurt her". Only, I looked over as I was going to say it and she had the BIGGEST smile on her face. I let him continue his playing and she kept smiling and squeaking away. I think it may be a 6 week old baby version of a laugh. That Wes sure is a funny guy.
