Re: When do size Regular pf's fit?
My DS fit into premiums at 3 months and outgrew them at 5 months! That being said, he's a BIG little guy. Premiums are supposed to fit from 15-30 pounds. If you are a SAHM, I say keep them for the next baby, if not exchange them for infants. I work, so I only use PFs during maternity leave and opt for the infant size.. then we move into fitteds.
