How is momma doing?? Keep a good eye on the incision.
My girl is 4 days postop from her c-section as well and I had to take her back once already for a small hole in her incision and some draining. She seems to be doing well now, but is not finished with her antibiotics yet either.
Just keep a good eye on her belly and call the dr if you see anything that doesn't look right. Hope her and babies are doing well!!!
Would love to see pics when you can!
