Fridge Invader

Let us explain a little something, this photo was taken this time last year. Cooper was just getting used to standing on his own. We loved this picture, and thought it was the cutest thing ever.
Yeah, but now? Not so cute.
Our independent little boy opens the fridge, gets his cup out, peruses around, and even proudly brings us the gallon of milk when he needs a refill.... Now how do we stop him from all these fridge activities?
