Re: How long was your baby wearing Mediums?
My 14 month old son is still in a couple of medium FB's. I sold off most of mine at 12 months thinking he was almost out of them. Then he slimmed down and he's back in them. The rise is short though (he's 33' tall!) so I'll be moving towards all petite's soon. Most other diapers we're in larges (SEZ, GAD). The fit is so different in every diaper. I think he'd be in a medium FF, but we haven't tried them.
