I've got a bawler! And people dare to talk of "how to" discipline

Sheer terror grips me when S starts crying. Which is very often these days.
He's two months short of two years but still, the Terrible Twos, i swear, have set in. He screams, he cries, he scream-cries.

Last night it was a tantrum to go to grandpa's place soon after we reached home from grandpa's. Then came potty. And S inistsed, bawling all the time, that he would go potty only at grandpa's!!!! So there he was running around all over the house pooping away on the floor, and refusing to sit on his potty :-(

And this was after he spent a good 20 mins crying for a water bottle (which hadn't been cleaned. He just wouldn't take "no" for an answer. I always give in (I know u're not supposed to and all that discipline blah blah) but at the end of a looong day's work, you just want him to shut up. I slapped his bottom. Didn't work. I picked him up and spoke to him in quiet tone and in very certain terms told him that he can't drink from the bottle. Didn't work. I screamed at him. He screamed back louder and stronger. Hubby tried playing hide-n-seek with him. S played, but screaming and with tears rolling down his cheeks anyway.

I was a cry baby too and now i wonder what kind of torture my parents must have gone through till I settled down.
