Jaykob does this when we go out in Shauns f150, because he sits in the front with us (its a ute bench seat) he has a chance to grab the steering wheel before hes been strapped in, so as soon as you go to put him in his seat, he arches his back and chucks a big tantrum!

I definitly think babies can throw tantrums !

lol

Good Luck
