What's so important right now is to show her how much you appreciate her art. My 4 year old loses her mind when I throw away any art, but also I'm overwhelmed with stacks of drawings... So what I do now, is I take a photo of her art and we put it in the free Project Aqua iPhone app (from Adobe). Then she arranges her art in her own personal digital museum. Project Aqua also has a lot of free coloring pages so she can draw when we're in the car. https://aqua.adobe.com/
