In Afghani culture they eat (Mum and visitors) a sort of nutty pastey kinda thing flavoured with cardamom after birthing but the Mum isn't expected to make it - someone else makes it for her. It's full of protein and fibre so it's pretty good for you.
I guess if you're in that nesting mode and you've cleaned your house 4 times then making gifts might be a fun project but I sure as hell wouldn't expect a gift from a new mum.
