I think yes & no myself.

I worried about SIDS because of knowing someone whose son died from it. But I didn't get a mat or a monitor or anything like that. I just checked the SIDS website & did the best I could without living in total paranoia. I'm someone who could go overboard with it.

I find that if I worry too much about the "what ifs" I lose the "what now". I mean that if I spent all my time worrying about every little thing that could affect them the rest of their lives, I could miss things that are happening right now, memories that can be made of positive experiences and love.
