My boy is turning 1 in a week and I want to take him off of baby bottles and offer him milk in a cup instead. However, he’s always had a reaction to cows milk and he still gets rashes from consuming any cows milk ie. in yoghurts or if he consumes large amount of cheese, even if given 1oz of cows milk.

I don’t know if I should take him off of formula or switch to soy milk or another milk substitute. Are milk substitutes as nutritious as cows milk? Will he get enough calories from milk substitutes?
