To anyone who has had a C-Section

Hi ladies, not sure were I could've posted this but I'm just shy of 32 weeks. I have a C-Section scheduled for April 3rd. With my daughter I had a natural birth. And the chances of that happening again are slim because I'm having twins and one has been breech this whole time. Anywho I read that you have to avoid stairs after a csection. Is this true? Because I live on the 3rd floor and now I'm stressed out because it never occurred to me I'd have to avoid stairs. How's the healing process and would this even be possible or would I be confined to my apartment for awhile? Thank you for any advice 🙂
