There are a lot of activities which you can indulge with your child to them smarter. Like playing or reading with them, ensuring they sleep well, exercising both physical and psychological (like problem-solving, decision making) or making them do household chores, or enrolling them for skill-building. Skill-building courses need not necessarily be curriculum-based or the most commercial ones. There are other skills also which make the children competent in the future. Some of the courses that we have are Unlocking Emotional Superpower, Public Speaking or Being A Great Detective or Owing the Stage
We at Cue kids (an initiative by Simply Body Talk) encourage kids to remain great observers throughout their life by helping them to enhance their understanding and reading body language. For this, we have a lot of activities in the form of camps or party events ranging from public speaking to emotional intelligence or making them great detectives and lots more.
