Here's a little comparison. This is Owen 3 days old: Here he is at 4 months old:

Owen had his 4 month check-up on Tuesday. He now weighs 15lbs 14.5 oz and is 26" long. He also got 4 shots, so we had one cranky boy Tuesday night! His favorite thing right now is to squeal and blow raspberries. He also loves sucking on his hands, which makes for a slimy drooly mess most of the time. I'm surprised he's not drowning in his own puddle of drool with the amount that leaks out of this kid!

Here's a photo of Owen bonding with our original baby. They are becoming good pals. Ruby loves to sneak him little kisses here and there.
