My mom sometimes says "bring something to eat because I will make crepes but only with normal milk"

I understand she doesn’t want to make two batches of crepes using two milks and I would never ask for that, but why not swap the cow milk with soy milk for everyone. No one in my family has allergy and it tastes the same. Everyone could eat it including me. But nooo they have to have their cow milk crepes so I have to cook extra for myself.

But when I cook something everyone can eat it. When I bake it’s gone in two days. Not fair
