You're not a babysitter

Contrary to what many people believe the first five years of a child's life are critical to the rest of his life.

I'm not sure why it should be a surprise.

Almost everyone understands that a building needs a good foundation.  The better the quality of products used and the better the craftsmanship, the better the building will turn out.

Feed a child grass-fed meats or healthy proteins, good quality fats from butter, coconut oil, olive oil, cod liver oil and egg yolks, as well as complex carbohydrate-rich foods like vegetables, whole grains and legumes and fruit–think whole food, natural and seasonal, with a big emphasis on healthy fat. 

A healthy body has a healthy brain and that should be the next focal point.

Talk to him.  Read to him right away (if for no other reason than he will start to equate reading with cuddling and happy times.) Giving him information at this time in his life is like dunking a dry sponge in water -- he is engineered to just soak it up!

After these basics, the most important thing you have to give is yourself!

Baby animals grow up in the wild imitating their caretakers.  Baby humans are geared the same way. It's just natural, a built in survival technique, but if you take advantage of it you can make it so much more!

Parents are so much more than just babysitters, so don't wait for school to teach him what he needs -- you might be too late.
