Nathan seems to have been piling the weight on every week but he seems to have slowed a bit now. He still drinking his milk fine so is it normal for them to start slowing down at this age. He is now 15lb 8oz at 14 weeks and he has only gained 10oz in the last 2 weeks. I know that is fine but its a lot less than he was gained. It takes Aimee about 3 months or more to gain that, LOl.
