I saw another momma friend with these booties for her little one. Hers had velcro that made getting them on and off quick, from the picture you can see that these have snaps so I was a little hesitant, and right to be so because it is difficult to button over pants. Also there is no fleece on the inside, so they are not as warm as expected. The 6 month size barely fits my 4 month old so order big. I would return if my husband hadn't already washed these for use.
