I've been told there is a rule about having cots three feet apart from each other while napping, but is there a rule about the storage of cots? We have the interlocking cots and they are being stored in my supply closet. My closet is tiny, and it is virtually impossible to get to my supplies with the cots in there. I'm thinking about clearing a corner of my room to store the cots. I would cover them with a blanket or tarp to deter climbing from the children. Is this against the rules?
