Certainly your post is very interesting and coherent, many times children take these attitudes where the modern father as you mention do not take into account the reactions of these little angels, also I have a niece who will be 2 years old and you are right in the sense that 18 months begins the aggressiveness in them that if at that age is not controlled tend to do what they think, really very good I will tell my sister to read it, best regards.
