Up until DS has been quite happy eating from his tidy diner (wooden table so it doesn't stick down properly), ah but no more. Now he rolls it up, chews it, flips it, throws it and basically its driving me mad. I've been putting his food straight on the table but he drops it everywhere. Not a chance I could give him a plate, suction bowls no use bloody table again. Should I just buy a new table and be done with it? I've got a tripp trapp highchair and I'm sure the trays are really expensive, any ideas please?
