What Is The Treatment For Vomiting?

Hi I fed my 9 month old 2% milk early this morning around 11am ..she seemed fine until I fed her a bowl of quaker oatmeal , she's thrown up 3 times now , a large portion at first nd then the second was not as much as the first , and third time was a small amount ..she usually had oatmeal before bed on a regular basis ..but when she threw up there where large chunks of milk ..anything i can do to help soothe her stomache?
