If you don't have some sort of degree in education, child development, psychology, ect, you are incapable of teaching anyone anything, ever. Only those with the proper certificates, and have spent thousands of dollars towards their education in said areas, have any possible hope of someone learning something from them. I never learned anything from my parents, who didn't have degrees in any field, or my grandparents, aunts, uncles, friends, friend's parents, ect. Anyone that has taught me anything has had the proper certificates, plaques, degrees to prove that they themselves can teach and be learned from. So it has been since the beginning of time. Since God, who himself had all of the proper degrees, graduated Adam, the first person, and, the first person ever to earn a doctorate.
