Guys,
What you're talking about is the confinement period. For 30 days after the birth, the mother and child aren't really supposed to leave the house. This is because of the belief that the mother's body has been severely weakened by the birth, so this period is to help her build up her strength again and to help with providing food for the newborn. Whether this is necessary in this age, maybe, maybe not (this tradition goes back at least hundreds if not thousands of years), but is still practiced.
How each family practices the traditions is different. For example, there is the belief that the mother should not take a shower (she is allowed to wipe off) or bath as that will open up her body to catching a cold or flu more easily (remember, many of the houses in the countryside don't have the bathroom in the same building as the rest of the house...and little heating back then). Others... no fried foods...and must have red-date soup among the foods consumed. Others believe no "heating" foods...
Besides, remember that many of our cultural quirks are also strange to them...
