My wife just told me the other day that she was pregnant. She was addicted to crack as a teen and I am afraid that the baby will grow up being a crack baby. So as a dedicated father I want to find out as much as I can about crack babies and all other related subjects. So far my search has been successful except for that no one can tell me how docters can tell it is a crack baby by looking at it in the embriotic stages of development. Can you explain this to me please?
