Hi! Sorry to start off with something so sad,

I have had two sons that both passed away. The first passed from SIDS and the second passed from a very complicated congenital heart condition after lots of surgeries and procedures. Because of the heart condition his breathing was fast and crazy at times and we saw him in many scary conditions. I have been around other newborns and babies since and when I hold them sometimes I get really scared that they’ve stopped breathing when they’re perfectly healthy and sleeping just fine. Im about to have my third baby and I really want an 02 monitor for peace of mind for naps and night time sleep. What are your recommendations on what’s worked well!? im not necessarily I retested in the owlet because I’ve heard so many bad things about them
