Its not easy at all to raise a child. It seems like you can do better until you actually have one on your hands. The only thing I would do differently would be to teach the little me how to be self dependent.
Having the clone of myself as a baby, will be an interesting one for me. I will raise him in a way that he will have a courageous spirit, especially in the midst of his colleagues. He will be a better version of myself
I think I we train up the clone in the same ways my parents brought me up but better, the places my parents where lacking on, I would definitely include them to the training, the little mistakes they made, I would try my best not to make them as well.
