My mom was the same way she would get really angry with the constant badgering. That is untill we found she had a serious sweet tooth for Kozy Shack rice pudding. I am serious we would walk in to a store and buy four cases just to last the week. Sometimes the best thing you can do is play a little tial and error untill you find something. It took us awhile to find the right thing but when we did that is all she ate for the longest time. Don't worry you'll figure it out:)
