Yeah, but at 18 months that was already the case for mine. In fact worse because she spent more time on the ground probably.

Well my daughter is the youngest of four cousins and gets tons of clothes we then pass on but, and maybe it's a lifestyle thing, coats tend to be one of the things that don't last well. Baby age yes but after that she's wearing it every day without rotation and at daycare/school they spend lots of time outdoors in a muddy playground.
