Reply To: source for not buying stuff for a baby before its born needed

sam4321 and Chani T- Check out the sefer Nishmat Avraham- (written by a talmid of R’ Shlomo Zalman Aurbach as well as a talmid of the Shemiras Shabbos Kehilchasa)- who brings that very medrash and cites it as a proof for those poskim who DO allow one to find out the sex of a child; Since the parallel Gemara does NOT list knowledge of the baby’s gender as one of the things not known to man, we follow the Gemara’s version over the Medrash and permit one to find out their baby’s gender.
