I'm keen to get some wax crayons for my LO. She's only 7 months so I need something non toxic just in case she puts it in her mouth. I've seen the bees wax crayons made by Stockmar which sound ideal but they are quite expensive, I think they're only available on line and I've never seen or used any. I remember using Chubbi stumps crayons when I was a child. Are these less safe for babies? I cant find a list of ingredients for Chubbi Stumps so does anyone knows what's in them?
