This happens to everyone. You come across something and wonder, 'Why didn't they have that when...'. So this thread is dedicated to that.
And, it happened to me the other day. I came across this baby monitor, and wondered, 'why didn't they have that when my babies were little?' The PREE BabyM.A.T. has video and sound like others, but also monitors the heart and breathing rate, all wirelessly. It also sends you an alert if the breathing or heart rate drops low, and lets you initiate a vibration stimulation to awaken them enough(think sleep apnea). I wish I would have had something like that 10 years ago. It would have saved me from the paranoia of SIDS, and getting up to check on my son several times a night. I suppose its just the natural progression of technology though.
