5 months old!

My baby is 5 months old!! How can he be growing so fast?? I don't have an official weight, but I'm guessing he's about 18-19 lbs., as he has a good appetite. Jack likes to talk to his Mom and Daddy. His new thing is a high-pitched squealing. It's super cute! He has almost outgrown his 6 month clothes. Guess it's time to go shopping again! I'm so glad I have such a happy baby. The boy smiles and laughs all the time. The only time he is fussy is when he's tired. He still sleeps all night- from about 8 p.m. until 6 a.m. He rolls over in his sleep almost every night, but we've still not seen him actually roll over. I wait with the video camera every morning, hoping to catch it on film, but he's a stubborn baby. He can pretty much hold his bottle by himself, which is amazing. We are working on sitting up... he can sit up by himself for a minute, before falling over. hehehe. Jack gets cuter and cuter every second of the day. We could not imagine life without him.
