My son is 22 mths and he refuses to sit in his highchair. He has two siblings who have never had this problem. If i just strap him in against his will he hurts himself trying to get out. Distraction has no impact whatsoever, whether its me dancing around or giving him toys. I havent tried brand new toys but that could get expensive. He will decide to get in if there is food on the tray but then he has about three mouthfuls and screams to get out. Ive tried letting him out and allowing him to wander around the kitchen while his siblings eat (and making sure he has snacks and things at other times) and hoping this thing will pass, but he just ups the anti and demands to be carried and keeps changing his demands (let me up, let me down, give me this) until i cant take it any more. Its driving me mad. As im sure you all know i need this time when the kids are in the highchairs to cook, unload the dishwasher and tidy, not to mention paying attention to my other children. Any ideas?
