Basically coloring designed for children from 4 years. It is necessary to offer the child a few options for the different colorings. It happens that some of them are out of child’s interest, while others will love it. So try to pick up the coloring in accordance with the interests of your children.
Coloring, of course, cannot be banned. You should not exclude its use for fine motor skills; this activity allows parents to get an extra half an hour of free time.
