When dd1 went into a bed and swapped to the room next to ours she can call out and I hear her. She is also able to open the doors to come get me if she needs too.

Dd2 is 13mths and we still use it, although the sensitivity is right down, will prob keep using it until she goes into a bed. She did throw up about a week ago but she didn't even cry so I think it was in her sleep didn't notice until morning the poor darling
