Interesting to hear your experience Baroness.
I used to live in Africa, and the tradition for new mums and babies (at least in the region I was in) was called 'lying in'. It involved the new mum and newborn moving back from her marital home to her mother's house to be cared for, for 30 days. They were given the best and comfiest room in the house and didn't leave that room - normally a bedroom - for the 30 days.
Well-wishers and visitors came to visit them in their room, bring gifts, etc. The new mum's mother and extended family would do every bit of housework, cooking, including care of her husband and other children, needed. Those 30 days were just for new mum and baby to bond, breastfeed and recover from the birth, within their little womb-like room.
Oh yes, and they have special porridge ceremonies around the bed where visitors all share a celebratory bowl of special porridge with the new mum, who usually stays in her pyjamas.
Although I think the 'lying in' tradition would give me cabin fever, I appreciate the reasons for this tradition, especially of not exposing the post-partum mum and newborn to any risk of disease or strenuous activity (whether it's cleaning, caring or ploughing the fields...)
I've never heard of 'lying in' taking place in Europe though.
