Sprog will be two in a couple weeks and I've seen no reason to stop the onesies. She only wears them under overalls, though. All her pants are knit and I'm not fond of the onesie-under-knit pants look on her now that she's more "kid" and less "baby." She has a little pot belly and big cloth diaper bootie, so it's not real flattering.
They're super-practical under overalls or jumper-style dresses, though. Not sure what we'll do when PTing starts in earnest.
