How do you keep calm with your 2.5yo?

Hi ladies,

How do you keep calm with your 2.5yos testing your patience? My little girl is in a phase of not listening and chucking tantrums the moment she is told no or told off for doing something she has been told multiple times not to do.

I'm finding myself increasingly irritated with her and my patience is alot less because of how constant the not listening/tantrums are. I'm 23 weeks pregnant aswell and not sleeping very well at night, so the lack of sleep is probably adding to my short fuse at the moment 😫
