Linc's first babbles

After a solid 2 months of us saying, "Lincoln, say da-da." Or, "Lincoln, say ma-ma" he has finally started babbling a little bit. He has a vocabulary of 3 words. Ma-ma - which he only says when he is crying. Da - da which he likes to say in the early mornings or when I use the phone during the day. But his favorite word is "blah-blah-blah". Is that all he hears when i speak? He is just like his da-da!
