Unfortunately we are not so enthusiastic about the pram chain. Sure, it is colorful and makes our regrowth also a lot of joy. But our parents makes them more worried. For our little ruffian scratched (involuntarily) the paint of the figures from. Partial but crumbling this also from the edges of the holes through which the rubber belt runs. However, since our young chews a lot on his hands and sucking, we fear that he "eats" the paint under his fingernails. That can not be good. Addition: I've turned me to the manufacturer, who also responded. He took me some concern, said that the colors are made water-based and are not dangerous. All toys are "saliva", which does not mean that they should not be solved.
