My newest grandson was born with club feet. At nine days old he was casted on both legs up the the top. He can no longer have regular baths. The problem is his messy diapers are getting on the white casts that cannot get wet. My daughter has cut up tube socks to put a two inch banding on the casts but there is a lot of fuzz getting in the baby's private area. My question is, isn't there some kind of sleeve banding that I could use to make these little bands? I don't know what you call that to try to find it or do you wonderful people have any other suggestions? Thank you!
