Our daughter brushes her teeth by herself. I would out the amount of the toothpaste and she will do the rest. She is four years old. At her age, she is very good in brushing her teeth. It takes longer than two minutes for her to brush her teeth which are always a good idea. After done brushing her teeth she Would gargle some mouthwash. I am glad that at her early age she is doing the right thing taking care her teeth. This way, her teeth will be clean and healthy. Brushing is very important.
