Re: Time out for a 19 month old?
We have started time out with our older two when they were 12 and 13 months. It was used only for hitting/kicking, dangerous behaviour etc. Stuff that was not negotiable and that redirection did not help. I know that they understood. My oldest started doing what you are describing around a year and we were able to eradicate the behavior within weeks by just consistently putting him in time out and repeating ,"no hit, nice touches only". IMO if they are able to sit there without getting up and modify their behavior even a little bit that shows me that they know they know clearly what we expect.
