Anyone else not super excited to tell their parents/in-laws?

My MIL watches my son 3-4 days a week and drives 45 mins-an hour to do it. I’ve felt guilty about it forever but she insists she doesn’t mind. She’s visibly tired a lot though and it feels like there’s nothing I can do. We are working towards me not working but can’t afford it yet. Anyway - I’m afraid when we tell her she will just be worried about having another baby to watch. That won’t be the case because we will figure something else out but I’m still worried about her reaction before knowing that. :( I just want everyone to be excited like we are. All children should be celebrated.
