Do women start producing breast milk as soon as they are finished puberty or once they have a child? and when do they stop?

usually women will start producing breast milk while she's pregnant... the milk goes and come... if u keep breastfeeding your baby "nonstop" the milk will stay...and keep reproducing...but when you stop breastfeeding the child for goodit goes away until your pregnant again

Well, l think that some effective communication is, emotional barriers and lack of attention, interest distraction or irrelevance. also some physical disabilities such as hearing problems or speech difficulties.      l hope i am correct  and you good luck.
