FYI, don't trust a 2 year old alone with parts of your cake competition entry. Don't get me wrong; I have a great kid. I suppose I set myself up for this one.
Sometimes I work on my competition entry in the kitchen and leave my stuff out. My daughter will come along as ask what it is. She's about 2 and 3/4 years old and is used to seeing "Mommy's toys" out on the table. She sees me working with gumpaste and asks if it's Playdough. I explain that it's a lot like Playdough and Mommy is using it to make things. I let her have a piece and have her squish it. I explain the shaker has powder in it to make it not sticky. She gets to roll the gumpaste around on my mat with powdered sugar. I explain to her that Mommy is letting these other pieces dry so they can get hard. I tell her not to touch those pieces and she nods, fully understanding. I go to the bathroom and come back, then noticing one of my pieces is gone ... she is squishing it and pushing it around on the mat. Luckily I had made 3 duplicate pieces "just in case" and she had grabbed the one that I didn't like that much. After a brief exchange of me expressing my shock, we both got over it and moved on. We enjoyed playing with gumpaste together.
Oh well. At least she didn't eat it.
