Yep mine is a screamer. We try a lot of redirection instead of just telling him to stop yelling. It usually works and gets him distracted.
I know some parents try to match the screaming, to make the toddler realize how silly they look/sound. Not my first choice or preferred go to option by any means. Similar to throwing yourself on the ground and emulating their tantrum. I prefer to lead by example and portrait a calm energy. Also, trick from my mom, cover your ears and say "ouch, that hurts my ears when you yell like that". That, oh that really resonated with my little one this summer. He paused and looked at her, and did not resume his tantrum/screams after that. Sure he had other incidences, but all were met with the Ouch that hurts my ears. And he would settle. So I've been using that as a "healthy option". Alternatively, we've also introduced timeout about a month ago, that has shown some success as well. He's learning that when he's calmed, he can come out. When he moves from the spot, he is brought back and has to stay until calm. 1 minute per year of age. So he's only there for +/-1 min. Every time he moves the time starts over.
My now 4 year old has a verrrryyyyyy loud voice. That I swear you could hear blocks away! He does the same thing. He screams and then tenses up his body. Although for him, he is on the spectrum so that has a little bit to do with it. However, when he does this, I usually hold his hands together and give him a nice firm hug and quietly tell him its ok to be upset but no screaming its to loud too, just some calm reinforcing words without yelling or I give him a firm hug and say do you want your Blankey? Do you want your susu like whatever at the time is his comfort and then I’ll say OK let’s go get (said item) but first lets try and stop yelling…. Doesn’t always work but sometimes. If we are at home and he’s doing the yelling sometimes I will just leave him in that room safety and go to a different room and say ok you can yell get it out and I ignore it and because I don’t give a reaction he tends to stop. It can be overwhelming in public spaces.
If he is tensing his body he could be in pain. Does he have bad gas?
Hello! Mine doesn't respond to negative feedback very well, so I try to use a lot of enthusiasm to dissuade him from being more "angry." He really likes trains, so when he has a meltdown for who knows what reason... I would be like OHHH WHATS THAT SOUND? I THINK I HEAR THE CHOO CHOO! LET'S GO, LET'S GO SEE! It helps take his mind off of why he is frustrated 😠 I hope it helps you as much as it helps me 🤣
