Thomas is four months old and today we went for his well-baby check, where I found out his latest stats:
weight: 18 lbs 1 oz (91st percentile)
height: 26.25 in. (89th percentile)
head circumference: 16.5 in. (55th percentile)
In other words, he's a bruiser!
Our first four babies all weighed 15 pounds and change at four months, so Thomas is significantly bigger.
Look at them rolls!
Thomas can sit tripod style for four seconds and can roll front to back but not the more difficult back to front.
