At times I get into this craving when I only wanted to eat nothing but vegetables, fruits, sour soups, salty, pasta/grains, and meat. And I also notice that my kindergartner is the same way. Very weird because we are supposed to eat with a mixture in the food pyramid. Mostly the vegetables and salty stuff I eat on the summer months.
My son in the other hand can go with everything on the table, to nothing but cereals and crackers, then meat, and potatoes. It's like a cycle. Anyway, I thought I would share my observations. TTFN.
