I can’t sleep- HELP!

Hey mamas, my owlet stopped holding a charge, (this happened 2 months ago too) I’ve been checking on it all day and it never got past 2% charge today.. but I did call owlet support this evening & she will be sending a new sensor. My baby just turned 5 months a few days ago and I’m having the worst anxiety- I did last time too- but more so now because 2 girls I went to HS with lost their babies to SIDS (one at 5 months, the other just turned 6m) I am so tired but I can’t sleep without this thing pulsing green next to me ☹️ plus, with the holidays I don’t expect to get it until after Christmas 😩
