I feel your pain. Once, years ago, I was making homemade brown and serve rolls to have for Thanksgiving the next day. When they were ready to be removed from the oven, I put them on cooling racks, on the kitchen counter, closed the baby gate and went to dust the living room. The next thing I know, my 11 month old has climbed the gate, pushed a chair over to the counter, climbed up and BITTEN EVERY ROLL! So what could I do?
I served pre-bitten rolls for dinner (it was just family, anyway), stacked another baby gate on top of the first one to make climbing harder, and started getting gray hair.
You will laugh about it one day, but you will grit your teeth a few times between now and then. :)
