How old is ur daughter? Children generally have tendency of vomiting if they have to travel soon after they eat.
Google search for home remedies. One simple solution is give her small piece of ginger and honey immediately after she finishes of her breakfast. Just mash the ginger a little bit so that she can swallow. Ensure that she finishes off her dinner atleast 1 hour before her bed time.
