Hi, I do not have any DC's so I don't know but I do have a DSD. She is 3.5 yrs old and is a good sleeper, I have know her 10 months and she has only ever woken up twice, both times when we had just moved house. I ask because the monitor causes me to not sleep, I can hear DSD snoring through the walls let alone through the monitor and last night it started flashing because the room dropped below 18 (DP put the heating back on after) this took ages to stop and by that time I had given up and gone and slept on the sofa. We have to have it with us at all times, even when we nip out the front door for a sneeky fag when she is in bed. The dissition is not mine to get rid of it I understand that but I could bring it up if I know you don't always need one for a 3.5 year old. If you do I will just carry on not sleeping well untill she is older. Many thanks
