Pregnancy resource centers and maternity homes often accept gently used children’s books and toys, newborn and infant clothing, maternity clothes, and other items. Look up the organizations nearest you (just Google your city and “pregnancy resource center” or “maternity home”) and call them first to find out what items they accept and how they’d like those items delivered. If they don’t need what you have, ask them for recommendations to similar organizations that might be more interested.
