5 year old

I have the worst behaved 5 year old little boy. He’s so spoiled and I try to best to correct it but all he does is cry cry cry cry cry cry cry and I mean cry this kid will cry for 2 hours all because you told him to go get ready and brush his teeth. He hits he pushes. And I do time outs I do spankings I take this away and NOTHING works he will get back up and do the same thing he just got in trouble for. He screams in my face he cries over eating cereal. He had 2 friends sleepover last night and he has done nothing but sit in time outs for hitting and talking bad. I’m 9 weeks pregnant and as much as my boyfriend helps with him. I think a screaming new born is easier then this screaming 5 year old. We can’t take him anywhere because he will cry the whole time. I don’t know what else to do. And parenting thoughts or comments please.
