Hi....I recently started my 6 MO baby on formula milk but she gets rashes around her mouth and neck as soon as I feed her. I tried different brands but reaction is same On doctors advice I started giving her cow milk diluted with little water and she is tolerating that very well. No rashes and good digestion also. Isn't formula milk made from cow's milk??? I just want to understand if anybody faced similar issue??

Thanks for help.
