Keeping him in his chair

We do have problems at meal times with children not staying in their chairs. We have tried various things but I think J might have found the solution on his own.

The shirt was stretched in this event but it already had a rip in it. Our local hole inspector has become a rip inspector and she notified us that it was ripped. Trust me if you have a hole keep it away from the hole inspector because she will make it a bigger hole.
