my baby is about 10months old .she getting immediate vomiting after drinking cow milk or other milk why?

A. First of all animal milk is not recommended before the age of 12 months secondly maybe your child is unable to digest milk that you are giving I do not know what is the other milk apart from cows milk but I think your child could be having a digestion problem which is why your child is vomiting it out immediately that me the system is not accepting the milk
