I'm trying to buy diapers and clothes when I find them on sale, but I'm not sure when growth starts to slow. Right now they seem to still be gaining about a 1/2 a pound a week. They're 10 lbs 10 oz and 12 pounds 2 oz right now at 13 weeks (9 adjusted-not sure if that matters for this).

How old was your LO when they slowed down on how quickly they grew?
