We are always carting around my daughter's monitors to homes that do not have one. It seems like such a chore especially because there are wires and plugs you have to deal with and its just another thing to try and cram into her diaper bag. This is why I love the NScessity Compact Audio Monitors. These small (size of an egg) monitors are battery operated, come in a cool case and are SURE to fit in any sized diaper bag. (via Baby Gadget)
