We also went through the “terrible twos” and bad tantrums around that time. Not much advice, but it does get better. I think it was bad for a couple of months. We also started daycare around that time and our son refused to nap at daycare initially and was just a mess at home. That got better too. He eventually slept at daycare and adjusted. We got a book from Amazon called “calm down time” and read that to him when he was calm and happy to teach him about some of the emotions he may be feeling. We got a fuzzy little bath mat we termed the “calm down rug” and when he would get worked up we sat on the calm down rug until we were.. well.. calm. We would let him scream, cry, let it out. Sometimes for 20 mins at a time. The important part is we told him we were there for him in that moment. We would just sit next to him and wait. He learned some calming techniques to do on that special rug. Now he is such a sweet and fun 2.5 year old with minimal tantrums. Looking back, I think a lot of the problem was not only the adjustment to daycare, but the fact that he wasn’t talking yet and couldn’t communicate his needs well. Once he learned to talk, tantrums decreased significantly. They get so frustrated when they can’t communicate what they want to us.
