My DS, an only child is driving me mad right now, throwing things, anything on coffee table gets chucked, he throws tantrums when things don't go his own way, is now able to slide out of his straps in highchair and tries to climb out! But the main thing that causes me stress on a daily basis is him throwing a berky if i so much as pick up laptop, run mater in kitchen, when he is in lounge, or if I hoover or switch on hairdryer!!!! It's got so bad I have to make sure I only use hairdryer if he is sleeping, he is fine when DH is home, but takes great delight in winding me up. He is not like this when he is at his Gran's which upsets me more. Can anyone help????
