I didn't mean discipline as in spanking or time outs or any kind of punishment. Just how you would teach a child "no". And when I said more strick, I mean that I'll tell the one year old no to probably more things than my sister would. For example: my sister lets the 1 year old play with a hammer...a real hammer. I wouldn't let that happen. She lets her climb up on a step stool that's counter height. Again, I wouldn't allow it.
