Ok, I'm guilty....call me every name in the book....but I used to smoke around my daughter (cigarettes)...she's five now and she's had ear infections every year. Oh the guilt! I was a stupid fuck!
I, on the other hand, was raised around second hand smoke but never had a single ear infection. ~I've since stopped doing this so don't give me too much hell~
While my ex-wife was pregnant she used to smoke a couple a hits of marijuana every now and again. When my daughter was born she slept through the night from day one on. She hardly ever cried and has turned out to be one bright cookie. (She was walking at 9months, talking at 10months and started reading a month after she turned 4years old.)
