I have an Angel Care one too and still use it with my 3 year old. Our house is big and when we're in the basement, we can't hear her in her room. We don't use the movement mat anymore now that she's in a toddler bed but we used it until she moved out of the crib. We got the occasional false alarm but do we REALLY know they were false? I don't know. Anyways...we'll use that for new baby once he/she is out of the bassinet.
