I look after this beautiful little boy who just doesn't stop for breath, he's like a whippet & kangaroo rolled into one, he's now 4 as athe grandmother I observe a lot he's become so aggressive, he now throws his head back or bites or pulls a demented face before headbutting floor, he's changed so much my daughter in law decided when he was 2 she was gay so was already with the lover my son was fine it was over anyway, she now continues to drop him every weekend but leaves him, always a good excuse, she turns up when she likes but thinks we will all quiver as the new partner resembles the honey monster, could this new aggression BTW he does not fall asleep be down to physical punishment and what should I do
