my daughter is 2 years old. she's doin vomitting on eating food. but she is eating Maggie , chips and all. what to do

A. Hello mom as she is able to eat the other foods which are unhealthy and still she is okay And not vomiting that means that she is doing fine if she really had food intolerance then what ever she is been consuming she would have puked it out so it can be just a tantrum or a way to just avoid eating normal foods and eating what she is preferring.
