My MIL has offered us a cot- great news- expect that it turns out that it is made of metal, not wood like I expected. Apparently it's a seventies design classic, in which all three of her sons (including DH!) were happily raised. No-one can understand why I am unsure about this gift- won't a baby hurt itself chewing on the bars? Anyone ever used a metal cot and can advise? Am I being unreasonable?
