I have a grandmazilla

I have previously had 3 miscarriages. (previous relationship) New relationship & now I'm pregnant, we are both very happy! But this is the 1st grand baby & great grand baby. His mother is already planning a gender reveal party & buying gender neutral clothes. I'm only 7 weeks.! Idk what to do.. I told her about my previous miscarriages, but that doesn't seem to slow her down any.
