"I got this gown because it looked so cute and cozy, and it is. But it has one major flaw that I didn't consider when I bought it-- BEFORE my baby was born. It opens from the top. You have to toally undress your baby, basically, to change its diaper. My husband and I have *loved* putting baby in gowns at night, so we can easily just pull them up and change our daughter's diaper, without fussing with snaps or upsetting her. But this gown requires basically a full undressing. I recognize that it is called a "bunting" (not "gown) and that the bag part provides further warmth for the baby. However, we achieve the same thing by putting a zip up bunting bag over a regular gown, and baby never has to be undressed. This gown/bag is the least-used of all her sleepwear."
