Amy, don't be alarmed if your daughter is changing her preferences every hour. That's what little kids do. Besides, it's lots of fun to watch Mom get upset!
An 8-month-old baby is still receiving most of her nutrition through breast milk or formula, so she is not lacking for nutrition. Unless she is losing weight, let her decide when she wants to eat her solid foods. She's almost old enough to begin table foods and will make it very clear to you when she's ready to begin again. Please don't let her actions make family mealtime a difficult time. This will resolve itself soon.
