HELP! High Chairs and Toddlers??

They make high chairs that actually attach to the table, that might be an option. Then he's actually at the table, but he can't get out. Otherwise, it might be time to just get him excited about sitting at the table like a big boy. He's old enough for a time-out if he gets out, and if you get him excited enough, and maybe go buy a new booster seat together it might just be what he needs! target has restuarant style high chairs as well
