These pajamas are great but thin...so if you are in a cold area it may not be warm enough for your baby.  Where I live it's been hot and humid during the day and slightly cooler at night so these pajama's are good.

I like it because it's so much easier to change my son's diaper in the middle of the night with the zipper opening from top to bottom.  We also have the Carter's pajama's which take a little more effort since it has snaps all the way down.  My husband complains about snapping the buttons.
