Best bed wetting alarms out there for kids?

My son wet his bed until just about a year ago. He was roughly 10 when he stopped. Our insurance said they would not cover an alarm, the best bet is to ask your insurance company though, every single one is different. We found something that you might want to look in to, or think about. My son seemed to have accidents no matter what we did, reduction of fluids, making sure he used the restroom before bed. He had seen multiple doctors, when one finally asked if he was allergic to milk. We said yes, he had been as a baby but had grown out of it. They did an ultrasound on my son and found that even though he was having bowel movements, his intestines had fecal matter hardened on the sides, and the pressure from the bowels (that were also inflamed slightly) was pushing on his bladder and would make him urinate with out him even knowing, at night it pushed harder and that is why most of his accidents happened at night. We put him on soy milk, removed all milk products from his diet and cleaned him out with a children's laxative (the doctor gave it to us) and he hasn't had an accident since then. I am not saying she is allergic to milk necessarily, but that problems we would never associate with bladder problems can be the source. Good luck
