When did you stop buying toddler sizes and move up to the kid section? I ask because we're straddling that line. Both children need 5T for their tops and in some cases for their bottoms (read: diapers are bulky, DD, please potty train). But I know the time is coming perhaps in the next year when we'll be making that leap to youth xs-s.
How old was your LO when you made the switch?
