This is a great post! I have been signing with my daughter for about 6 weeks, she is 10 months old. She recently started signing eat and milk. She seems to get it but doesn't do it all the time. She smiles when I sign to her like I am is doing something special. When I sign milk to her before I get her the bottle she giggles the same way as when she sees her bottle so I think she knows what I am saying. I am going to print this post to keep there is great info in here.
Thanks!
