I'm wondering how old your LO was when you stopped putting them in onsies?
DS is coming up to be almost a year. Do over 1 year olds still wear onsies? Or is that a baby thing? I know sizing goes up to 24 months, but not sure if I should buy him some onsies for this winter or just stick with long sleeved shirts.
When did you stop putting your LO in onsies?
