I went to a bbq with my 2 month old and some people were smoking near to us. I moved away from them, but could still smell the smoke so decided to leave, but not until we’d been there for the best part of an hour (albeit in the open air and they were not smoking the whole time). I’m a very anxious ftm, and as soon as we left I panic googled the effects of second hand smoke and have really scared myself- specifically about the link to SIDS. I really don’t know why I didn’t leave earlier, I guess I was just enjoying being around people for the first time in ages and didn’t really think about quite how harmful smoke could be for tiny ones. Needless to say, I feel awful and won’t make this mistake again, but does anyone have any info about the potential harm of a one-off exposure such as this? Thank you.
