Birthday woes—- help a momma out 😩

Hope I’m posting in the right place. So my daughter turns 7 on March 9th. I am having a scheduled Csec less than 2 weeks later. I am currently 31 weeks today and feel so uncomfortable and huge etc way more so then with my 1st. I keep thinking what if he comes early or if this is how I feel now I can only imagine another month will be way worse. I want her day to be special but not wear me out. We went all out with an over the top bday party last year and this year I was going to take her to go get her ears pierced and then make a day of it celebrating her with just me her dad and my mom and dad. She has since said she doesn’t want to get her ears pierced but wants to have a slumber party. I like to plan parties and decorate and go all out (coo coo right lol) and I am really not against having 3 girls over but the way things are feeling with my pregnancy the more I am dreading her birthday and what to do. Can any of you moms with multiple kids whose birthdays are close together tell me what y’all do/did when baby being born so close to their sibling. And also can y’all help me with my dilemma on what I should do/ ideas for her bday that would make both of us happy. I just feel like a bad mom right now cause I really don’t feel up to doing anything 😢 thanks in advance.
