I know exactly what you are talking about not moving beds, drilling holes, etc. But my in-laws are luckily not as aggressive as yours and my husband usually sorts out all these issues with his parents rather than me.

Well, to be honest what about your believe system? You didn't grow up with Chinese traditions and it is difficult for us to understand their beliefs. And I still don't except all of them and do what I think is right to do.

I mean the infested bed is a serious thing and poses probs more health issues to you and the baby, needless to say all the fumes from the pest controllers. I am sure they are extremely toxic and very bad for you and your baby. Get rid of that thing...and you don't have to be there when the bed is taken out and the new one moved in, that's ok to my understanding of this superstition.
