Tallon was 6lb, and he wore 0000's for a fair while. We moved into 000's even tho they were a little big.. but good news is... we've been in 00's for aaaaages now! The growth slows down after a while He wears some 0's, but mainly coz of the cloth nappies, pants need to be up a size... hehe. But 00 t-shirts fit just fine. Haven't had to buy clothes in ages actually!
