Everett has grown 6 inches in 4 months!!! Here are his 4 month measurements. The length is a whopper, but we're going to "watch" the weight. For now, nothing to worry about as he is healthy and happy - just has a long and lean body type.
Weight: 13 lb 14 oz (25th percentile)
Length: 27 inches (upwards of 95th percentile - in other words, off the charts)
Head circumference: 42 cm (48th percentile)
And for comparison, here are his 2 month stats:
Weight: 12 lb 7 oz! (75th percentile)
Length: 24 1/4 inches! (90+ percentile)
Head circumference: 40.5 cm (50th percentile)
Eric reminds me that these growth charts were standardized in the 1970's, so with each generation getting taller and taller, the average really isn't 50% anymore.
