Terrible 2s!?

[MissesG23]

Looking for some advise! My little boy has jst turned 2 and we have a new arrival in the house, she is just a few weeks old! My once angelic, happy boy has turn in to an absolute Antichrist :( I knew a new baby would be tough for him to get used to, his poor little world has been turned upside down and he prob wondering why is this other little person is not going away, but I’m at my wits end with him :(
Towards the baby he is very lovey dovey, but when me or my husband have baby he jst lashes out, bites, screams, kicks, scratches, can have a complete melt down jst like that or else he is doing ‘bold’ things that he would have never done before :(
He is not talking yet and is having a hard time in creche too and getting very frustrated and taking it out in the kids there. I feel before baby arrived he was getting a few words but now it’s like he gone backwards and it’s jst complete babble
Is this normal behavior, might sound silly but is this what the terrible 2s are?
I’m almost afraid to meet up with friends etc as afraid he might bite or lash out at one of them or their kids :(
I don’t know how to deal with him or how to discipline him when he gets like this :(
Any suggestions on making things easier or anyone gone through the same??

I have a 2.2 year old son who is a nightmare at the moment (I’m currently hiding in the bath and have been since my husband came home half an hour ago!) my sons talking is good and he doesn’t have a sibling so I don’t have those excuses! Getting him to do anything at all is such hard work, he whines, cries, shouts, says no, runs away, cries for daddy, won’t share, pulls my hair and doesn’t want to do anything other than play trains. He currently hates his nappy being changed, getting dressed, being pit to bed, putting shoes and coat on, leaving the house, eating anything that is remotely good for him... etc etc etc! It’s so hard. I have no advice- bought a book called how to talk so little kids will listen which is often recommended on here and it suggested giving options eg would you like to wear your brown coat or blue coat? Hasn’t worked so far... I would welcome anyone’s tips on disaplin at this age at the moment I say no and walk away but then he just screams and runs after me. Sometimes he goes quiet and then says sorry, so I think consistency with this might work well.
