Oh the many flavors of crayons

Emma loves to color. Recently she has developed a craving or two for those crayons. I've tried taking them away from her one by one when I catch them in her mouth, but honestly it isn't working. She is eating a lot of crayons these days. I don't want to put a damper on her creativity but seriously I'm starting to wonder how many crayons are too many crayons to consume.

P.S. Red is her favorite flavor :)
