Up until the age of 7 children are literally living in the trance state. This state allows the brain to download experiences quickly and easily. This is why children learn a skill or a language much faster compared to an adult.
Children take things in through their eyes and ears, but they are also very sensitive to the energy around them, picking up if their parents are stressed, angry or displeased.
There is no filter to their brain, so they pick up anything and everything, whether it is beneficial or not. However, when something does go wrong, they are just as likely to respond quickly and easily to hypnotherapy and positive suggestion.
Telling stories is a great way to help children. And children respond well to EFT either on themselves or via their favourite teddy.
