I would say that the paint is babyproof or safe at least, espcically if the cot is to AS. There are alot of cots that come with a plastic strip along the top to help with chewing, so maybe you could find out from the localshop or supplier or maker of Lily's cot to see if they can get one to fit on hers?
I think its just one of those things. It'll be us in a few months I'm sure!!
