Happy 5 months Keenan!

I can't believe Keenan is 5 months old already! He just had a dr's appointment a few days ago. He is 15 lbs and 26 3/4 inches. He's getting some chunky thighs! He still isn't rolling. He rolled two times from back to belly months ago and never again. I guess he's lazy. He does these crazy sit ups though. He's starting to sit for a few seconds on his own so I'm thinking by next month he'll be able to sit alone for sure. He smiles all the time. He is still throwing up like crazy. The doctor switched his meds and told us to give it a week and if there is no change then he'll switch it again. He has gone through 4 outfits this morning. It's ridiculous!
