Just seeing this response to my post now.
sycamore54321 in most of Asia there is a tradition of "confinement" where women are expected to rest, mostly in bed, for 30-40 days post-partum to build up milk supply and recovery from delivery.
A day in bed is not going to put anyone at risk of DVT, don't be ridiculous. I had a c-section under epidural and didn't get out of bed for 24 hours after having my daughter. "
Being immobile is EXACTLY what puts you at risk for DVT. And in the first six weeks after giving birth, a woman is twenty times more likely to get DVT than at other times in her life. It is really serious. Talking about confinement periods in Asia doesn't really add anything to the discussion unless you tell us the maternal mortality rate from pulmonary embolism and the morbidity rate from DVTs. Have you never seen the advice to wear compression socks on long-haul flights, even ones of six or seven hours? A period of several hours immobile is sufficient for life-threatening DVT. Telling a post-partum, post-surgery woman to stay under her baby day and night is a really risky thing to do.
I followed the cluster feeding advice - sit on the sofa and feed feed feed. I had zero other risk factors. I had life-threatening DVT, hospitalised in high-dependency medical ward (without my 20-day old baby, due to infection risk), six months of painful injections, two years of follow-up treatment, and lifelong health consequences. Because I followed the exact advice people are giving the OP (and I was lower risk than her, having not had a section) and nobody ever told me of the post-partum risk.
Scoff at it all you like but blood clots are in the top ten causes of maternal mortality.
