Is it possible for the pillow to develop mold after some time?

Molds may form when items are left wet and unclean, but may be inhibited in Polyurethane Foams. Like any other Polyurethane Foam pillow, you need to ensure that it is cleaned when soiled, and dried well. The advantage of our nursing pillow foam is that, it is made of closed cellular foam which repels water or moisture up to a certain degree. The closed cellular foam will prevent the water or liquid from penetrating the inside of the foam. So, if you clean and dry the liner completely and maintain the integrity of the foam, the foam will last for a long period of time.
