Tantrums, Help

I already spoke to our daughter's doctor about our concerns and have been doing what they recommend. Her tantrums are so stressful for all of us.

She does the following:

Throws things

Breaks things

Bites

Screams

Kicks

Pinches

Scratches

Punches

Pulls her hair

Lays herself on the ground

Pinches my boobs

Its not all of the time, but its gotten to the point where we cant go eat out and I dread being home alone with her because it's so much stress. I am 36 weeks pregnant and a SAHM. I'm at my wits end. We give her tons of love and attention and try to include her in all of the cleaning and work around the house we do as long as its safe, etc. This started only within the last few months. She used to be so nice and gentle. I don't understand what has happened. She's not jealous of me being pregnant. She actually is very protective of my stomach and is quite excited about "baby sissy". Any advice please! We miss our nice girl. Shes so hard to spend time with..

*Yes we know "terrible 2s", this is beyond some learning stage though. Shes become a completely different child.
