NEXT Baby Romper and Overall Set 6-9 months 74cm My daughter, born in February weighing 2544g, wore these from 10 months to 1 year old (around 8.5-9kg at the time). The crotch has snap buttons for easy diaper changes, and the shoulder straps are adjustable in two stages. There is some pilling on the ankle area of the quilting, but they are still wearable. I am also selling other children's clothes, so please check them out as well.
