Thanks for the reassurance - we will def keep it on til he goes into a bed I guess.
I dont know how we will sleep without it - was kind of asking about when ppl turned it off as i was worried we were going to become too dependant on it and perhaps most people already would not be using!
We turned up the sensitivity and moved the sensors a little last night and no alarms.. so a better night here. thanks again for the info/advice.
