To announce as a gift or no?

Not sure how to start this, but I guess with background, I have mental health issues and miscarried a little over a year and a half ago. My mom has been a huge support in my life with my mental health including helping me go to a rehab (my choice) for emotional issues, but fast forward to that pregnancy, my husband and I weren't married yet and were not very financially stable. Somewhat, but she still helped out a lot. What she hasn't really supported is me having kids. She's always been concerned because of my mental health that she would end up raising my child and especially that they would have my issues. She doesn't dislike my problems or discriminate or anything, she's just seen how difficult it's made things for me and how some of the poor decisions I made affected my family and brothers childhoods, and doesn't want anyone to have to struggle through it. We lost the baby 3 months in, and she seemed so relieved, and kept saying the time wasn't right and we werent ready (which was definitely true at the time!)

So fast forward to now, I'm 7 weeks and 4 days, we are more stable, and my husband wants to announce it as a Christmas gift after watching my parents with my cousin's new baby the last few weeks. Which is a great idea! Normally, but I feel like with my issues and just especially my mom it's going to be more of a "oh crap, I mean yay!" gift. Am I psyching myself out? I was 19 then, I'll be 22 a month before my delivery, and we've matured a lot. I feel like we are ready now, but I'm also torn on whether or not she's gonna be HAPPY about it, especially Christmas morning.
