Help, I’m So Stressed And Worried About My Kids?

Ever since I had my 2 daughters, 3 yrs old and 9 months old, I worry about everything. I don’t know how to relax. My latest worry is that we had new carpet installed in our living room and I had no idea that it is really bad for our health. Apparently there is formaldehyde in the carpet and it ‘off gases’ into the air. I’ve heard that it can do this for a long time, like months or even years. So I’m exposing my babies to this crap? I don’t know what to do…my husband told me to calm down and it’s not going to hurt them but I’m worried. We didn’t buy a high quality carpet…just something on sale at a carpet warehouse. What should we do? I can’t just up and move, but I’m so stressed out about this. I’ve heard it can cause long term damage…any advice? Will this carpet really harm my girls?
