Don't feel bad for posting this, at all! You have every right to be hurting, and I would be a blubbering mess around a baby at any age right now. (Hence why I'm doing Christmas hermit-style this year).
This is going to be a tough day for you. And I'm so sorry. Do you they know about your loss? You take as many breaks from that baby as you need to. ((((HUGS))))
Thanks! They all know about our loss. DHs entire family is here. I haven't even seen the baby yet. I think DH is trying to find us a hotel for the night
because I know I can't stay here tonight.
Good. And, IDK your DH's family and how they would respond, but it might be helpful to be up front with them and just say "hey, I'm having a hard time with this. Just a heads up, but I might need to take a few moments. It's not about you, it's about me. Please try to understand." Or something. Just to take the pressure off and relieve some of the guilt you're feeling about "ruining" their holiday (which I'm sure you're not!)
