tantrum toddler. HELP

Oliver is seriously driving me to the point of freaking out.

He throws these huge tantrums. Doesn't listen. Ever. spanking doesn't help. Ignoring tantrums doesn't help. He entirely ignores redirection. Time outs don't help because he won't sit in one spot ever. Let alone fucking listen to me.

My temper and patience and so short lately. Not to mention pregnancy hormones and stress.

I'm at my wits fucking end.

He also doesn't have his own room so it's not like I can lock him in his room until he acts right.

Someone help me.
