Extra big thick maternity pads, pop an extra one in over your scar stuck to the inside if your knickers.
It will help draw out moisture and prevent infection. Also acts as a bit of a padding so you can press it when you need to pop, cough, sneeze ect.
2 C-sections for me and not a single infection; midwife I saw during recovery said it’s more than likely because I had a maternity pad over it constantly during healing.
Get some cotton pads (not balls) and spend a few minutes really dabbing across your incision line after a bath/shower to dry it. Also don’t put body wash directly onto it, wash your upper half and let the soap just wash over the incision, then rinse really really well.
Move little but often, try getting up and pottering the house, making your own cup of tea ect.
The massive difference between the recovery of my first and second section:
first, I was scared to move.. laid on the sofa for weeks and didn’t move much only to toilet and shower and recovery took ages, the full 12 weeks before I felt normal ish again.
Second section: I got up, wandered around a bit every so often had little walks only into the garden in the first few days. But by day 5 I wasn’t taking anymore pain meds, not even paracetamol. And by the 2 weeks mark I felt like I hadn’t even had a section at all. It was night and day difference.
