I’ve always bought clothes too big for kids/babies, on purpose. If a kid is 3 months old I would buy 6-9 months probably. A 6 year old I would buy either 7-8 or 8-9My friend mentioned a while ago that she was going to buy my baby an outfit as part of her Christmas present, so I told her what size she’s in now but also suggested getting the next size up as she’s getting big quickly.
Opened her gifts to find a selection of lovely winter clothes in sizes 12-18 and 18-24 months. My baby is 3 months old![]()
