Oh no..

We've just been invited to a family "thing" that has the potential to be quite awful. A cousin and his wife are home for a few weeks from Hong Kong. They had their first baby last summer. His brother and his wife have a 2 year old, concieved shortly after we started trying.
In short, I feel uncomfortable with this part of the family b/c I am significantly older than my cousins. Their mother has, several times, said "i want to see you hold the baby, so we see how you look with one". I know that going to this dinner is going to be a night full of people making comments to me about having a baby. I don't share my infertility issues with anyone in that room, so I just have to smile and take it.
I'm in a good place right now. Excited and hopeful. But the second I got this e-vite my stomach sunk. Problem is, LAST year when they were home and she was pregnant, I faked a migraine and cancelled. I can't believe I'm here a year later. Not sure what to do...
