we don't have one at all. DD sleeps in our room at the moment and our house is fairly small. our cordless phones have a room monitoring function, so f i have to go outside while she is asleep (if i have a load of washing to hang out or cleaning up the yard etc) i put the phone in our bedroom on monitor, take the second one outside and we have the third handset that will ring if someone calls. works really well, so i dont think we would need a baby monitor anyway when she does move into her own room.
