Out of control 2 year old going on 3

Graziella
My son is 2 going to be 3 in a few  weeks we have a baby coming in a few months and he is totally out of control. He doesn't fall asleep till almost midnight, he throws things and screams all the time. He is so hyperactive. My husband and I don't know what to do anymore. We don't have time for us as a couple or even alone time. I don't know if it's the baby coming terrible two's or three's. He screams unless he gets his way. He doesn't listen to anything and does things in a spiteful way. I'm crying every night. My husband is at a loss for words also. All day long he drinks water with very minimal apple juice. He used to drink milk all day I took that away. Help me please!!!! What do I do I want to talk to a doctor I am lost😢😢😢
