As young as two years old, you can explain to your child that everyone in a family has certain jobs to do and these jobs are very important. His job is to put his toys away when he is finished playing with them. You can help him at first by showing him how to sort the toys (also a great learning skill) such as the action figures from the animals. Be sure your shelves are organized and there is plenty of space on a low shelf that he can easily reach.
When he’s finished, make a big deal about what a great job he did and how helpful he is to you. You might even create a sticker chart that you will fill up with a sticker each time he cleans up. When you reach ten stickers, he gets a special treat, such as an ice cream cone, small toy, special play date, etc.
There are many jobs that kids can do at very young ages. You will need to add more responsibilities as you believe your child can handle them. Helping set the table, putting laundry away, and putting non-breakable groceries in the cupboard are all jobs that toddlers can handle. They will gain pride in helping you and will learn the value of becoming a responsible member of the family.
