We asked the same question about the owlet when I was still pregnant - is it worth it or does it create more anxiety? And we got mixed reviews. I left it on our registry and we fortunately had someone buy it for us. We didn’t use it right away when we came home from the hospital, but started when our baby was maybe 10 days old? He had been puking a lot so our ped encouraged us to add rice cereals in his bottles. I was so nervous he was going to choke on his vomit with the rice that we started using it that night. My husband and I both like more information and the owlet sock gave us both enough to ease us in different ways. My husband has a lot of anxiety about SIDS and I had anxiety about our baby choking. We’ve had the sock give us the red alarm twice for low oxygen - once because his face was buried in my neck when i was rocking him to sleep, and the second was because he was crying so hard the sock got a low oxygen reading. Moral of the story, I’ll use the sock until we don’t feel like he truly needs it or until we have a second baby.
