It doesn’t stop at terrible 2s , it keeps on going . But it will get easier . Have patients , find ways that work for you to handle the bad behavior and definitely reward the good behavior so your child can distinguish the difference between the two.
I mean tantrums will happen. It depends on your child. My toddler isn’t affectionate. She has her boundaries. If I try to rub her back or anything it makes her tantrum worse. I try help her talk it out. I ask her are you mad/sad/hurt etc. try to distract them. Remember to try to stay calm. Because the way their brains are it literally feels like the end of the world to them. They still haven’t learned to process their emotions like us. But as the parents we can try to teach them. Unless in public I try to let the tantrum just ride out. I tell her when she’s calmed down I’ll talk to her unless she wants to talk to me right then. (Usually not) lol. Also it depends on the reason. Did you say no? Are they tired? Etc. you kind of have to gauge the situation. I really do try to distract her and see if I can calm her down that way.
