Happy Half Birthday!

On January 2nd, Thomas turned 4 1/2. He got to have a "party" while at Nana's house after dinner. We had muffins and ice cream. Papa sang only half the words to the birthday song, which Thomas is still singing. He thought that was so funny! It's hard to believe that in 6 months he will be five years old. Why does it still feel like I just brought him home from the hospital yesterday?
