Baby Shower Dilemma...How would you handle it?

Boy this sounds like my own story! Really there is not much you can do about it, aside from hoping that his side of the family sticks with his side of the family socially and the same with yours. Since your family is already aware of their lack of stability they should know how to be pleasant while keeping their distance. I would however make it known that since this a baby shower whoever starts some bs will be asked to leave. It's you and the fathers day to celebrate your pregnancy you guys don't have to be considerate to anyone their that doesn't mean you well. And your boyfriend needs to stop giving his family the energy to think that they can be judgmental towards your situation and behave how they want. He needs to stand up for you and also stand by you. If at anytime someone on his side of the family does something at the shower you don't like he should be prepared to deal with them and have them excuse themselves from the shower. After all you are the once carrying the child and whatever stress effects you it also effects your unborn child. Good Luck!
