Oh dear lord i need help!

[kelpie169]

My 22 month old is driving me absolutely insane! He's misbehaving, he's biting himself, he's throwing himself down and screaming for seemingly no reason-for hours! No matter what I do he won't stop screaming. I've tried every kind I discipline I can think of and now I'm just at the end of my rope. I also have a 3 year old and a 7 week old so I can't spend 100% of my time with himi just need some help! Advice?
