Goat's milk is similar in makeup to cow's milk so should technically be
substitutable (is that a word?) The caveat that I've heard is that the
flavor is distinctive and not everyone likes it. You might try a few
recipes that only use a small amount of milk and see if your mom notices
and objects to the flavor; if not, gradually try recipes using more
milk. If she objects at any point, you know how much milk you can use
in recipes for her.

Or you could try using straight goat milk in something it would be
immediately noticeable, such as coffee or even a glass of milk, to see
whether she likes it or not.
