Here are our little guy's four month (well, actually 4 1/2 month) Stats:
Length: 24.2 inches (10th percentile)
Weight: 14.9 pounds (50th percentile)
He is really developing a personality these days. He is all smiles, but man is it hard to get him to laugh. He is a wiggle worm and loves to "stand up." He rolls over both ways, but mostly front to back. Most recently, he has become interested in toys. He is very entertained by the mobile toys and exersaucer. He is also beginning to track with his eyes.
He is growing so quickly!
