A year later my son broke his leg and so did chestnut.
Wait a second, can you explain to me how your son broke his leg?
My son's leg broke in the middle of the night, when nobody was with him, not even his mother.
Children can be careless so you have to be careful so they don't get hurt. If they get hurt you have to care for them so they heal properly and not suffer for the rest of their life.
I should have kept him quiet on purpose then, he deserved it for being stupid.
No, that is considered to be a terrible way to think about something like this! Your son should be the most special thing to you in the world, and when he is injured you should be willing to do anything to make it better.
