We had a long, harrowing experience at the doctor, complete with lots of screaming before he even got his three shots. Here's the update:
Weight: 16 pounds 12 oz (75th percentile)
Height: 25.5 inches (75th percentile)
Head: 17.75 inches (100+ percentile)
He's hitting almost all of his milestones, with the exception of those that involve tummy time. The dr. suggested 10-15 minutes of tummy time three times a day. I just laughed.
