Keratta Waterproof Sheet I bought this as a spare for daycare, but I never had a chance to use it, so I tried it once during a nap at home. Of course, there were no bedwetting incidents. There are a few pen marks on the back. Would this be suitable for a baby bed, naps, or daycare (o^^o)? Please understand that this is based on my personal assessment, so there may be oversights. For those who understand that this is a used item, Thank you very much.
