I think 14m is too young for time out and I am a big supporter of doing it early.
So far I think you are handling it. I think removing from the situation is entirely appropriate, too, as you have been doing. If she is doing it over a toy the toy gets removed.
In public, I don't know this seems like it is an overwhelming age in many regards to behavior.
completely normal. Tell her that we don't hit and it hurts mommy and then redirect. I also think you are handling it very well. It's a frustrating stage for them and us. They have feelings and emotions and don't know how to express. hang in there
imo, 14 months is too young for time outs. We were always advised 18 months was the soonest to start by the pedi.
I'll just warn you- mine is a hair puller and she thinks it's funny when I say ouch.
Mine is like this too. He started a hitting jag around 14 or 15 months. We would say "Hands are not for hitting." and redirect. If he hit again, I would hold his hands in mine - gently but firmly so that he couldn't really do anything with them- for about 30 seconds and say it again. That generally did the trick. The hair pulling, however...
