My almost 5 year is getting close to outgrowing 5T clothes, so going forward I was wanting to get her the next size up. In Carters/ OshKosh, is that 4-5, or 6-6x? She’s about 41 inches tall and 41 lbs, I think- fairly petite, with still the last traces of toddler chubbiness. Mostly I’m just looking at leggings that she won’t wear much before the fall.
