Did they just give her food made with alcohol lmao

In stews and things like that alcohol gets cooked out - so no alcoholic content remains so it's perfectly safe to consume even if you're a child. Cakes and deserts on the other hand don't reach the right temperature and usually aren't in the oven for long enough for the alcohol to cook out so deserts can retain a certain alcohol percentage while stews and things like that don't- hope this helps (=・ω・=)
