Concerning the x-mas tree..why don't you get a fake one ???Doesn't smells as good...but no ndelees everywhere and u can use it for years to come (if u invest in a good quality one they looks as good as real one ...)It was a huge dilema for me too concerning the vaccine but finally I'm going to have it done for my boy...The pedietrician saw kids in hospital with completelly ruined lungs and was horrified ...and that scarred me too...
