What are the Indian post-pregnancy beliefs and traditions?

so many! but some do seem as if they were made with keeping the mom n baby's health in mind....even though they are not really useful in today's time 1. the mother should not watch TV or read books for atleast 40 days after birth as it can harm her and baby's eyesight 2. do not go out of the room for at least 40 days and meet anyone to avoid any illness or infection 3. dont switch on the fan and definitely no AC 4. no cool bath
