I expected to love this, and love other Kickee Pants items, but the arms and legs on these feel particularly narrow. I am using this on my 21lb 30in tall 1 year old. She is a little bit chubby, but this feels the limbs are almost too tight. In addition, we can see the diaper through the fabric. I am a little concerned about the air flow through where the snaps are, but she seems to be OK with it. The arms and legs are too long since I ordered a size up, but I don't know if it will fit when it would have been the appropriate size.
