Does anyone know if the casein/whey cows milk protein can be found within processed lactose?
Some background: our 4-month-old baby was given teething granules. She was then presented with a rash, screaming, etc. When we checked the teething granules (called teetha) we found they contain lactose.
However, from reading it appears that lactose intolerance is extremely rare in the UK and cows milk allergy is much more common.
