I wonder do boys normally have bad temper, my nephew is naughty and also not very good temper, he seeks attention a lot and cries whenever adults are not within his vision. He likes people to play with him all the time and that is quite draining on the adults. Sometimes he can be a while crying and a while smiling, really don't know to be angry with him or not. Sometimes when he cry, his mother will ignore him until he stops crying on his own because cannot everytime give in to him
Sometimes he will stare into blank space and don't know what his little brain is thinking.
But I do observe that he learns things very fast, he learned his walking quite easily.
