I broke my son's favorite toy and he was very sad. What should I do?

If you break your son's beloved toy. So if he is sad now, then his beloved toy is broken. He is very sad, that's for sure. In this case, all you have to do is coax him more. That is to say, let him stop being sad and take him out as soon as time permits. Buy a similar toy, or let him choose other toys himself. Let him find something he likes, and then you buy it for him. In this way, he will slowly become happy again, and then secretly throw away the broken toys when he can't see them. His memory is very limited. With new toys, he will forget the old ones.
