I weighed N this morning. He gained 1 1/2 lbs over the past (not quite) 2 weeks. I haven't measured his height since mid-April so we remeasured him. He is now 5' 3/8" tall. He basically grew 1/2" in 2 months. No wonder his pants look short all of a sudden.
I've notice lately that weight is coming on more easily. It seemed like, at one point, it would take a month for him to put on a single pound. Now he can put on a pound in a week. Perhaps his hypermetabolism is slowing down a bit.
