I was desperate for some warm leggings for my petite 2 year old daughter to wear under a dress for an outdoor wedding in the mountains in December. You were perfect. So thick, warm and cozy. I've read other reviews that they run small. Definitely true. You need to increase the size. The 3T was a bit long but fit my daughter who normally wears 12-18m or 18-24m. They weren't as tight on her as regular leggings, but they were snug enough.
