Fathers day with husband's family

A
My MIL wants to do breakfast for her dad and my husband on Sunday, which is no prob at all..but I'm sort of dreading seeing everyone. Idk how many people will be there, and granted they're all family, but there's a lot of them I haven't seen in quite some time. I'm not looking forward to all the "wow! You're huge" comments and belly touches. I just want to be left alone to be honest. Is anyone else turning into a hermit the closer their due date comes? I love his family, so it's nothing personal. I just don't wanna deal.
