I admit I hadn't realised how bad things had got, until today. This morning my 3-year-old hauled the baby off his play mat and left him in the middle of the floor. He thought it was funny. I'd thought DH was in the living room with the kids, but wandered into the office. Then after lunch baby was sleeping in his bouncer in the dining room and I saw DS1 deliberately go up to him and shake him awake. There have been many other incidents of him violently bouncing the bouncer when he thinks I'm not looking or hugging the baby too fiercely. He can never leave the baby alone - he's forever poking and prodding at him, saying mean things about him and just generally being unpleasant. I'm afraid for the baby and really starting to dislike my older child, which I feel awful about, but I feel this fierce protectiveness of the baby.
I've tried doing nice things with DS1, I booked him onto some fun things this past month to try and give him extra attention. When the baby sleeps we cook, read books, play games, etc, although there are times when I'm feeding or holding the baby and I know he's feeling neglected. But they both have to wait their turn for my attention - as all children with a sibling do. Does anyone have any advice? I'm feeling fed up and every time I leave the room now when I'm home alone with both of them I have to take baby with me - to the loo, to the kitchen to make a cup of tea - because I daren't leave him in the same room with DS1, unsupervised.
