When age do people stop putting vests under their baby's clothes?

When they’re potty trained most people stop using them

Once potty training

I stopped after the newborn phase

My 22 month old still wears them. Maybe when it gets to the summer I’ll stop.

Once potty trained, then still for a bit at night to keep nappy in place as LO thought it was hilarious to take it off 😬

I didn’t put these under clothing unless I was putting a cardigan or something over the top, or unless it was cold and needed a few layers. Otherwise these were just used as a top option and I stopped putting her in them when she came out of nappies x

Once my little boy was walking more than crawling we moved to normal tshirts instead of vests, he was a bit slow to walk so was around 20 months x
