Is you toddler a picky eater?

So I’m seating here crying feeling like a failure :( my 4&2 yr old girlsgirls eat only certain things and refuse to try anything else.. I have to give them milks eventually like after every “meal” bc they would’ve eaten nothing from their plates!! Some say starve then until they eat what’s in front of them but I just can’t do it. I had made eggplant one day put it in front of them ate it in front of them saying mmm so yummy.. nothing! I didn’t give them the milks they didn’t care just skipped lunch 😟

I don’t know what to do the two of them don’t even eat the same thing so I’m making 3 different meals each meal time and they still eat on their feeding chairs
