@ubersiren Um, well, just a thought. Try one way or the other, 100%. Either the instant he starts screaming dump him in his room (or do you have another room downstairs to put him in? A laundry room or something? A closet? JUST KIDDING on the closet.) OR find the strength and willpower to ignore it from beginning to end….(I remember locking myself in the bathroom while I hyperventilated in anger! I remember locking myself outside! Srsly!!) It just seems to me that it’s important to be 100% consistent in this….
Thing that I’m thinking about now is, I think you can get it under control in the next three months, but if you don’t it’s going to get 10 X worse, for you AND for him. For you, because of the stress and tiredness of having a new baby AND having to deal with the screaming from your older son, and for him from the stress of having competition in the form of the new baby. And even if you get it under control, it’ll probably flair back up when the baby is born, but if you handle it instantly, the same way you did “before” you should be able to get it back under control pretty quickly. Oh, good luck!
