I think this is a great suggestion.
My nephew was hyperactive, had itchy raw patches on his ankles at age 2,
and within
two days after being taken off dairy (my suggestion) he was a different
child!
His little brother wasn't give dairy until age 2 and you've never seen a
calmer, sweeter child with beautiful skin, who, BTW is still
breastfeeding "nummying" at age 3.
