Children can’t start learning guitar before age 7 years. This is common misconception with no factual basis. You only have to look at an instrument like violin which in my opinion is more difficult and starting at age 2 years is almost the accepted norm. Children can start whenever they can hold a small guitar or perhaps ukelele to start.
Guitars are expensive. I am still surprised by the number of people who say they want to learn guitar but they can’t afford to buy one. You can buy a basic guitar for about the same price as dinner for two at most restaurants.
