Question?

Hi just wanted to know if anyone else has had this problem. I have almost a 3 year old and I just found out I’m pregnant. But she had been having major meltdowns and I don’t know how to make her stop. You tell her Liz please don’t do that or no that’s not good and she breaks down in tears and runs off like if something very bad happened. I try to redirect her to do

Something else but she just won’t budge. Also side note she does not speak yet she’s in therapy. But she has Improved. Does anyone have a recommendation for me?
