Terrible 2 (normal or not?)

Raychel

My son is 2.5. He’s very strong willed, a bit advanced with speech and is pretty smart. (Can count to 10, knows ABCs etc). He has multiple tantrums everyday. Sometimes all day long. Hitting, throwing things, refusing to cooperate or follow direction. Lots of issues at daycare. We are going to have him see a behavioral specialist but could this be normal even though he seems extreme? We are exhausted. I’ve read all the books, tried all the things, and we are at a loss of how to survive everyday.
