Owen just turned 4 months old a few days ago, and he just had his regular visit with the pediatrician. While he looks so much leaner than his old brother did at this age, he's actually a little larger. Here are his stats:

• Height: 28 and 1/8 inches (75th to 90th percentile)
• Weight: 16 pounds, 3 ounces (75th percentile)
• Head circumference: 44 centimeters (90th percentile)

In addition to being bigger than Oliver, Owen's athleticism has a head start on his brother. He's already rolling over and, despite our efforts, sleeping on his stomach at night. And also unlike his brother, he actually sleeps well at night at this age.

Owen's generally a quiet baby, content with entertaining himself often (usually because Oliver is so darn needy and an attention hog). However, when he decides he needs some food or needs to go to bed, he lets out the loudest, shrilly sound you can imagine. Between the noise and the way he moves his head about, I call him our little velociraptor.

Overall, he's a good kid and we love him - giant head, dinosaur noises and all.
