During that free time, encourage your child to play with their toys, make up creative games, play dress-up, go outside, read a book, or whatever else they like to do with their time—as long as they're the ones in control of the time.
Avoid letting your kids fill up all of their free time with screens. A little technology use during the day is fine, but too much screen time can discourage children from using their imagination.
It doesn't matter if you don't have 80 million toys for your child to play with. It's the quality, not the quantity of the toys that counts. In fact, at times you may find that your child is more content playing with an empty toilet paper roll than the fanciest toy they own.
