Toys scattered throughout the house are a familiar environment in the apartment of young parents. The child does not see the point in cleaning, because the game continues all day, and getting toys out of the closet is so boring.
Don't raise your voice. Shouts and swearing are unlikely to help in this matter, education should not be reduced to tyranny at all. Remember that by yelling at your child, you, of course, will force him to remove the toys, but you will not help him realize the need for this process.
Explain to him why you need to hide toys in the closet. Mom can talk to her daughter about how she needs help with the household, and she is already old enough to take part in this. Dad will explain to his son in an accessible way that mom cannot have time to monitor the whole house alone, and the boys' duty is not to pollute the house to facilitate her work.
Make cleaning a game. There is nothing better than continuing the game and not doing boring cleaning. For example, you can go to the forest for mushrooms. Scattered toys will be mushrooms in this case. Or tell your child that there is a nasty boy in town who steals other people's toys at night. Therefore, they certainly need to be put back in place after the game.
Create a toy house. They do not have to be closed in a closet, arrange your own corner for baby accessories. Tell your child that all the toys live in this house, and they only come out to play with him. After that, they must be returned back, otherwise they can get lost and get lost on the way.
Emphasize that only an adult can clean up after themselves. These words have a magical effect on children, because they so want to be adults! Ask him to act like an adult after the game is over, and it will work instantly.
