In some cultures, there are lots of customs about a woman who has recently given birth to a baby, such as feeding special fancy meals to her, taking special care of her, and so on for (a certain number of days, e.g. 40 days from baby's birth) and of course there's a well-known word that explains this.
I couldn't find anything in the dictionary and thesaurus and based on my search keywords. Does it exist in English?
P.S.: The term new mother is quite general that won't refer to this certain period just after birth.
