My son Bentley was born 5 weeks early, & was 6 pounds & 0.5 ounces, 19 1/4 inches long when he was born. He is now 13 months old, & just 18 pounds & 8 ounces, 27 inches long. Just wondering if that is small for his age or not. Compared to his older brothers they were at least 33 inches & about 25 pounds at 13 months, if I am remembering correctly His 5 year old brother is 4 feet tall, & 49 pounds & his 3 year old brother is like 9 inches shorter than him & 45 pounds. Yes, I have some big boys.
my son was born at 38 weeks, 6lbs 4oz and 20in long. at his 12 month check-up he was 20 lbs even and 29.5 inches. so that doesn't sound too far off especially for a preemie. i wouldn't worry as long as he's gaining.
