Tantrums and teething

I have read a very popular parenting book that claims teething is a myth. That lady is mental. Owen is cutting his eye teeth and it is seriously messing with him. He is just not himself. I blame this for the disgusting tantrums I have been witnessing this past week. My god my boy can put on a patty!!
We went to Petrie markets on the weekend for my birthday and it was a disaster. He refused to sit in his pram and screamed like someone was strangling him until he got out! We let him walk but there was no way he was holding our hand and if we tried he threw himself onto the ground in a blaze of screaming, crying and shouting! If we let him walk on his own he would run as fast as he could into the crowd never to be seen again. Exhausted we eventually went home. Time to get strict with this monster, teething or not.
