My sister has given me a list of her "must have" activity items to register for- doorway jumper, bouncer, swing (travel size so you can take with you), entertainment mat, exersaucer.
She's also got a front carrier and a framed back carrier. I'm not sure I'd use a carrier at all, but DH might?
She's already given us a little bathtub (which I don't think we'll use) and a pack'n'play.
Any items that you think were a wash/waste?
