cow milk is allergy for my son ?so can i go through plant based milk ? if yes then suggest me which one is good?

A. Yes of course you can go ahead with any milk other than the dairy products you can actually check different brands available this way will be difficult for me to suggest you the correct plan you can check with your doctor also and if your child is small you can even try homeopathic treatment to get rid of the protein allergy or lactose allergy completely
