Idk how to deal with Josiah's tantrums lately... They're so BAD!! He'll scream, cry, kick, hit, throw stuff .. It's awful . . and the crying isn't just regular crying it's screaming bloody murder for lik 15-20 mins straight.. This is EVERY time he doesn't get his way.. I'm getting so annoyed by it because nothing we do helps.. We've tried redirecting him to something else.. We've tried ignoring him, we just take him to his room now if he's not doing anything to hurt himself and tell him to come down when he's done.. But getting him up there is a fight and as we're trying to leave the room he flips out and hits us, but then he'll eventually calm down and come back downstairs.. We have anywhere from 3-5 fits a day, I don't understand how a 2 year old can get this angry lol mauriz was never like this!! 🤦🏻
