The little guy is 5 months old today! The time is flying, and he's getting more fun all the time. He LOVES his sisters, and it's a good thing because they are always in his face. He's a pretty mellow fellow, and for the most part is all smiles. He's almost sitting alone, becoming interested in his toys, and enjoys lots of attention. Of course, who can resist giving attention to someone who listens intently and always responds with smiles and giggles. He doesn't appear to have any teeth coming in, but he drools constantly. (although I'm sure you've noticed that in his pics) He's tried a few food items, but doesn't really seem all that interested yet. Although considering his current size, I'd say he's doing just fine on his formula diet. I'm sure he'll change his mind about that soon. It's amazing to me how babies change and grow, and that in a matter of weeks, they can become so much more interactive.
