I went round supermarket on the way home 2 days after section, I felt totally fine but then I did too much and scar opened and had to rest for weeks! Don't do what I did take it slow, just do bare minimum til 6 weeks I'd say, teddy is 8 weeks tomorrow I've only started vacuuming, lifting shopping etc in last few weeks, been carrying Jesse from about 4 weeks and same with Carseat. I'm completely normal now just get aches if im doing a lot and sometimes get sporting after doing loads so I just rest the day after!
Hope your feeling better soon xx
