If parents only understood how the brain works! It would make their life a lot easier. For instance, research showed that if a one year old plays with the buttons on the TV while her/his parents are watching, parents often think the child is trying to spite them. It leads to punishment and unnecessary conflict. Young children are fascinated with objects and play with them when they can to find out what they do. Parents need to enjoy and assist that instead of getting annoyed.
Many parents rely too much on verbal communication, especially with young children. The may benefit from understanding that up till the age of 4 (more or less), the child operates as primarily right brain. The right brain has limited use of language and instead responds to non-verbal communication. That means coming over to the child, putting an arm around her and gently steering her to where the parent wants her to go. That means interacting with the child on his level: sitting down, squatting or at least bending over. As grown ups, we forget how tall we are in relationship to the child and how threatening it feels when a child has to look up all the time at the big shape over him.
