Do you feel disconnected from partner and children when with in-laws?

I’m not sure if I’m oversensitive but I feel so disconnected from my husband and two year old son when I’m with my in-laws. It’s like they are all a family without me and for some reason my bond feels threatened. When my MIL plays with my son and is holding him I feel disconnected from him. I am pregnant with my second and have anxiety so maybe this is normal pregnancy anxiety and territorial feelings but wondering if anyone else feels this?
