I ordered six pair of babylegs for my 3 month old for the winter.  My little guy is a little bigger than an average baby, but I figured since they said a six year old can wear them, surely my 3 month old can... WRONG!

When I put them on him, they were so tight they left horrible red marks and he started crying.  I took them off immediately and thought I might be able to stretch them out... no avail... I thought, okay, they say I should be able to wear them as arm warmers... WAY too tight.

Buyer beware, one size definitely DOES NOT fit all!
