Secret Agent Man

My daughter is, as we speak, climbing into the sink of the Fisher Price kitchen set, which is a good 18" off the ground. There was a recall on the item, but I don't think this is the danger they had in mind. She's such an animal. My husband is egging her on, laughing. Not so funny when it tips over and she bleeds profusely from her head. It's one of the many, many times during the day I am thankful she is active and adventurous, but worry about teaching her limits. Where to draw the line?
