Angelcare Monitor and Corner Sleepers

My boys tend to curl up in the corner of their cribs, making it hard for the motion sensor to pick them up. Oddly enough it's usually fine during the night, but in the early morning hours I start getting false alarms (which is GRRRREAT...). Last night the sensitivity on one baby's was at 4 (out of 5), and it went off around 5am. I turned up the sensitivity by 0.5 (as the manual says and I have been several times now!) to help solve the problem, but no dice - when I turned it on after changing it (he was in the corner, but I had repositioned him a bit closer to the middle), it went off immediately. Usually there's a delay of a few minutes at least! Any suggestions?

My daughter is a corner sleeper and we've only had a handful of false alarms the entire year. I never adjusted the sensitivity though so it is still set to factory settings and I made sure to put it in the very middle of the board under the mattress. Not sure if the new ones require you use a hard surface under the mattress to place the sensor on but if you haven't already that may help. Sorry I couldn't be of more help. Maybe if they favour a certain corner you can move the sensor closer to that side of the bed?

Maybe you need a bigger surface for the pad to be on? I believe the bigger the hard surface the sensor pad is on the more it will pick up.

Did you install a piece of plywood or anything under the crib mattress (I think that's what the instructions said to do?)

We never did, and ours never had that problem once we adjusted the sensitivity. But depending on what type of cribs/mattresses you use you may want to try that.

My DS started sleeping in the corners around 8 months and setting the alarm off. At that age I was comfortable with not using the motion detector and just used the audio monitor.

Thanks all. Yes, we have a piece of plywood under the motion sensor that is almost as big as the cribs on all sides.

I'm not comfortable turning off the motion sensor quite yet - I'd like to wait until 6 months adjusted if I can.

Maybe I'll move it towards the end of the crib they favour - worth a shot! Thanks again!

How thick is the mattress? DD is all over the place when she sleeps, but her mattress is pretty thin (more like a futon).
