FTM & SIDS

Hey y'all I am a FTM and my baby is currently nine weeks old. My husband and I do not co-sleep, we swaddle her in a sleep sack and she sleeps in her basinet every night. For some reason I have this overwhelming anxiety about SIDS. Am I the only one or do most FTM's have this anxiety? It makes me physically sick thinking about it. Are there any ways to ensure it does not happen? Or am I just overreacting?
