Question:
I'm currently a niddah and want to buy my husband a Pesach set for Pesach. Am I allowed to give it to him - I know we are not supposed to give gifts but this is something for this festival...
Answer:
It's fine to give the gift.
In general, it is permitted, even during the niddah period, to give gifts to one's spouse (this is ruled by the Kereisi U-Pleisi; the gift should not be of an overly romantic nature).
In this case, the gift is of a general nature (for the home), and therefore there is certainly no problem.
