Hi,
In terms of the practicalities of what to give your son for breakfast tomorrow - we are VERY fixated in our culture about what we consider "breakfast" Your son won't care what healthy food he has for breakfast. He can just as easily breakfast on pumpkin or fruit, or my personal favourite - boiled rice (ie boiled to a sloppy consistency). About a billion Chinese babies will agree with me. he might even enjoy the change!
