hi.. i have a 1 year old who has been on goats milk formula for the past 4 months, he was ok with that. I ve just put him on cows milk and find him a bit unsettled again, he has symptoms such as; hard stools and passing them more frequently, itchy skin, generally a little unsettled, do you think he has an allergy to cows milk and should i see a pediatrician? he had similar problems with his cows milk formula as an infant
