My boys have completely outgrown their gym mats with the dangly toys, unless an acceptable activity could be collapsing the top part on themselves, getting tangled up in the parts, and screaming. All of the hard plastic toys that they have are used as weapons. What kinds of toys do your babies play with that are soft enough not to injure the other baby. Right now I am constantly moving them out of each other's reach, which they hate even more than being hit in the head.
