This is the most perfect baby gift any parent could ask for. The alarm is shrill loud, goes off in 20 seconds if no breathing is sensed. My daugher has her monitor under a 6" deep crib mattress and it still works perfectly. I recommend this to any parent/grandparents who has a newborn. It gives me such a peace of mind when I babysit my grandbaby. You may think it's expensive, but look ahead at the cost of heartache if a baby dies of SIDS. Well worth the price....go in with a friend for a gift if you can't afford to pay for it alone. this is my standard baby shower gift now.
This sensor movement monitor was a LIFEsaver! It really gave my husband and I a peace of mind and allowed us to get some shut eye. If it weren't for this monitor, I would have slept with one eye open. We still use it and our baby is a week shy of 10 months. Just remember to turn it off every time you pick your baby up because that alarm sure does work ;)
