No junk food
Everything dr. Ferguson stated and i would add, do it as a family, everyone eats and snacks the same thing, donate the junk food and the sugary drinks, shop with a list and do not buy anything that is not on it.
Make it fun! do not use the "d" word (as in diet
) provide your child with life long tools to be healthy! let him help with food prep and maybe grow a little garden together.
