What size diapers are your LO's in at what age? This is I guess directed at disposable users since cloth doesn't really have sizes.
My LO skipped the NB size since she was over 9 lbs at birth. She was in size ones for a month or so, then the 1-2 size. By the time she was 3.5 months old she was over 15 pounds and in size 3 diapers. They fit fine in the waist, but the sides dig into her chubby thighs. I'm scared before we know it she'll be in size 4's before shes even crawling!
