Young kids aren’t capable of mixing emotions. The sky is blue and the sun is out OR they are in the middle of a nasty thunderstorm. It is either black or white. The process of maturation enables children to mix their emotions. It is when they are able to see things from the other side. I hate my little sister AND I love her. It is extremely rewarding and encouraging when you see this in your children. I am noticing it in my 6 y/o son. It give me confidence for my 2 y/o daughter who is in the middle of the terrible two’s.
