Yes, that is not a problem whatsoever. I have a huge experience working with children and know how to get their attention and make the lessons super fun. We take breaks, speak, and play mini-games related to chess that improve the child's logic and critical thinking.
Though it is true that depending on the age, sometimes the child finds it very hard to focus, but for that there is a simple solution too. We can simply make the lessons 30-minutes long, so the child doesn't lose interest.
