wondering if this is typical or not and any suggestions? my son will act like he is dying of thirst and we give him a drink and he lets it fall out of his mouth the sides, we have even cut his drink down to half a cup at a time. well now he is sick and we have been giving him more liquids to find his shirt soaking wet when he is done with his cup. i feel like i always have to have my eye on him when he drinks. i dont know what else to do, i have been taking his cup away the minute i see him doing this, sometimes he looks like he knew it was wrong and hands his cup over. other times he will scream bloody murder that we took it away but he is soaking wet. He has PDD and destructive behavior disorder. any ideas would be great, thanks!
