Keeps baby snug and warm.

I absolutely love Carter's Microfleece Sleep bag. Not only do they come in an assortment of colors and prints but they keep my little one snug and warm. If I Would have known how great these are I would have got more of these than pyjamas. You just place your little on inside the bag and zip it up. There's a mini protective tab on the top that keeps the zipper in place and theres cuffs on the arms making the sleeves fit snug. My daughter is four months old and will probably be able to fit in her 0-9 month sleep bags for another couple months. As a mother I could even imagine buying these as a gift and raving about them to other mothers.
