I REALLY like the owlette monitor, but I don't need to spend 250 on it (I saw it on Facebook) and I don't think an O2 monitor is necessary. I'm a habitual worrier, and I know once I have kids I'll worry about SIDS terribly. I looked up "movement monsters" out of curiousity and found this:
It can be switched to any onsie, jammies, or shirt with a snap and seems like it might be more reliable than the Snuza Hero (which I saw had a track record of falling off) and this one also has a phone app where your phone will alarm you.
