Well it didn't take me long to have to give it a try....
Sammy has this habit of hanging onto my pants to pull herself up when I am cooking or attemtping to do anything in the kitchen that doesn't involve sitting down with her to play ( which I do do a lot) So as usual, she pulled herself up and when I didn't pick her up or turn around quickly enough for her, she bit me on the calf/knee. So I picked her up and said in a firm and louder voice, NO Sammy, No BIting! and put her down and proceeded to ignore her. She threw a tantrum at me and I walked away. I was in the process to make a bottle for her too, so litterally ignored her and after 3-4 minutes, she started amusing herself again, and this is when I went back, finished preparing the bottle and gave it to her...

Is this following kinda what you meant Sarah? I just don't know how to ignore for too long as even though the house is pretty baby proof, I think we all know it never is FULLY and we shouldn't take our eyes off them for too long. Would appreciate a guideline as to how long do we ignore for??
