Hi, my ds is 1yr & 2 weeks. He eats unpeeled grapes and plums, but I still peel pears and citrus fruits. When is it safe to stop peeling pears and citrus? Also, when is a safe time to give him raw apples-should I dice, grate, slice thinly, give it o him whole to gnaw or wait until later? He has 2 bottom and 2 top teeth, another top 2 soon to appear.
