I'm hosting Christmas day, nothing major, just my young son, adult DD, her partner and my 2 year old grandson. Boxing day we will all be going to my mums. I really want to stay over at my mums boxing day night for maybe the Monday too, coming home Tuesday. But I feel so guilty that my adult DD will be on her own at home with grandson for 2 days as her partner will be at work working long hours. She already struggles with her mental health and finds being alone difficult, especially with her son. I already spend a lot of time with them but I just really want this time away at my mums, with my youngest, I've had a really tough year but I just always feel guilty about my choices. Aibu?
