Good part:

+ keep baby's feet warm
+leather upper
+stylish
+stays on baby's feet
+non-slip soles
Seem to be a good choice to have your baby wear them around the house at winter time. BUT........

Not a good part:

+they are SO SO SO tight. She is a perfect size baby rather thin than big, but she hates and i think i do to when i see the hard deep line around her ankles. REALLY SUPER TIGHT!
+if u put them into the washer ...well they won't look like before u did that
+faux lining which is not what i ever purchase and/or like

About true to size (she is tall 32 inches 16 mo.) and they seem to be a perfect size right now and i guess will be ok for aother month or so.

I say get UGG! Just like their boots, u cant go wrong if you want warm, dry, cozy, comfy, good-looking sheepskin footwear! Trying to save money u'll ended up with cold baby's feet, ugly look and getting UGG  later anyway:))
