Hi Karina. I can't comment on the retinopathy, but can do the c section and healing if that helps? I found it didn't take the full 6 weeks to heal, but I started doing too much to soon and delayed the healing longer than it needed to be. Days 1-7 are, well I'm glad I can't remember them much! Pain killers offered in hospital worked fab, paracetamol and ibuprofen at home didn't always hit the mark. But you have so many new baby hormones rushing around to not care. Days 7-21 felt a lot better but this was the time I started to do more. If you have friends/family that can help with the washing etc then please don't be precious - accept their help with open arms. Days 21-27 I felt strained having done too much. Days 27-35 I felt so close to almost being ready to drive again and so loopy at the prospect of being housebound. Days 35-42 I felt ready to drive and and get back to 'normal life' but I didn't want to push myself again so waited till the 6th week.
Biggest tip beyond accepting any help offered is making sure your cot/crib is a Co-sleeping one - being able to reach sideways and scoop little one out what feels like a hundred times a night is much less painful on the scar than sitting yourself up and then leaning over what feels like a hundred times a night!
