4 children. 4 of them if they have one, they will have 12.
One doesn't drink but maybe once a year. Two will drink about every other weekend. One will drink 28 out of 30 days.
Why worry? Educate as best you can and they will do as they want.
Alcohol in the tree or a dry tree... if they are going to drink, they take the risk. I can't stop them. It comes down to what choices they make after they are educated to the risks that could be ahead.
