PSA: The Owlet sock monitor is worth every penny if you're anxious about SIDS
Our daughter is 3 months old and I'm still in the paranoid phase where I check if she's breathing like every 20 minutes. Someone on this forum recommended the Owlet and I was skeptical about dropping $300 but honestly? Game changer for my anxiety. It monitors heart rate and oxygen levels and alerts your phone if anything's off. Might be overkill for some people but for us it's meant I can actually sleep instead of staring at a baby monitor all night. Just saying if you're a worrier like me, might be worth looking into.
Happy to hear this helped you. The paranoia at 3 months is so real that any tool that gives you even a little breathing room is valuable. Congrats on the new baby btw
