The days when your kid was not able to focus on one thing at a time is a thing of past now. As his brain and senses are developing, he is more likely to focus on one activity at a time and also bring his own innovations to it.
What you need to know
This can be really helpful in analyzing your child's area of interest at an early level. For instance, if your child is being more focused towards painting than learning numbers than clearly they have an interest in colors and drawing. Help your child by bringing activity books, games, etc. that will help in improving focus and also be a part of their activity.
