Positive discipline for toddler

Now I am not huge with discipline as Kaitlyn is still so young and is experimenting with things she does and how we react so I know it is all learning for her.

There are however a few things I say a "no" to they are :

*Hitting kids or our cat or me!
*sticking her fingers through the screen door and making wholes
*a soft no if we are at peoples house and she is touching things she shouldnt and I explain why she cant touch it.
* running towards the road or anything dangerous

Just wondering how you all positively discipline your toddlers , do you at this age?. And what for?

Am I to soft - MIL says I am ! or is it to young to be saying no?.

Praise :) Any age loves praise... my 10 month old *thrives* on praise. He understands no, but only listens half the time ;) But when he does listen I praise him alot. And he knows he's done good. So when you do notice positive behaviour praise her for that and soon you will notice a difference. Keep in mind that a toddler is learning independence and assertiveness so there will be days where you feel all you do is say no and there's the slightest amount of praise in sight. But I find something to praise for LOL! Its my way evening out all the no's... it makes them feel accomplished and me feel like not so much of an ogre.

Goodluck!
