My consultant told me they don’t recommend them as it hinders healing so I never bothered and I’ve been fine
They gave me a belt in the hospital and I wore it all day everyday for the first 2 weeks. Definitely helped alot! I noticed my stomach slimmed down alot better and faster this time wearing the belt. My first child was c section too but I didn’t wear the belt and noticed the healing and slimming took way longer.
Also doing core breathing exercises through the day while wearing the belt has helped so much !
I didn’t like it so I never used one and I had no issues recovering. I’d say at almost 2 weeks PP unless you’re having a lot of discomfort still, it’s probably not going to helpful for very long if at all.
