So my first born was 9lbs 11.8 oz 21 1/4 inches and my second was 9lbs 11.4oz and also 21 1/4inches. Now my first is 15months old and in 24month clothes...always been in the 85-90+% for everything and my 15week old son is filling out his 6-9month pjs....more length than width though. Just cant believe how huge my boys are...they look healthy and happy though!! :) just wondering how big your kids are :) feel free to share big or small!!
