babies with tempers

I have heard people say, sometimes you need to let the baby cry it out. However, in general, I do try to figure out what is wrong with the child first. My wife would tell you that I have far less experience in dealing with babies than she does. She would also admit that there are times where nothing seems to work. However, when we had our daughter, part of her problems seemed to be a need for antacid or antigas medicine.
