My now almost 5 yr old son used to stop breathing due to reflux.. We had an apneo monitor on loan from the hosp but bought a angelcare when he was a couple months old..

The thing to do first is before picking baby up turn the light on and check his colour.. Mainly check his forehead. It that has a dusky colour then yes he has had some breathing issue at some recent stage..

For Isaac we used a thickener is his feeds. he as having ebm. once we started on that we never had the alarm go off again.
