How to "tell off"a 14m old????

[Nicolaplus1]

My DD is 14 m old and i feel is allready quite naughty she has took to throwing everythingtoys, food you name it she chuks it and smacking she has now started smacking ppl in the face.

I feel i could tell her 100 times and it makes no diff is this just a phase?

I feel like she is too young to tell off but yet i know she understands the word NO and fully understand a lot of things now.

Do i just ignore it and hope it stops???

She will quickly move on as soon as she is distracted.

At this age I would use "NO" in a strong and firm voice (not shouting) together with a very stern face. If necessary move her away if she's in danger (like pulling something over or pulling the cat) or hold her hands so she can't smack.

About six weeks ago my 15 month old son crawled up to his sister aged 3, and bit her very hard on the arm. I scooped him up said 'No!' very firmly and plonked him away from everyone else in his playpen. This all happened very quickly within 5 seconds he was 'out' of the situation. He did it again a couple of days later, (less hard) and he was looking out for me. Again a firm 'no' and banishment (30 SECONDS TOPS). He has not bitten again (touchwood).
I think you have to be quick so they connect the biting with being removed from the fun.
As for the food, it will be chucked if she is no longer hungry and it will become a plaything. As soon as she stops eating it, put it out of the way and get her out of her high chair and distract her with something else.
Don't ignore her smacking you, because if you accept it she will do it with other children who will in all probability hit back. If she hits you put her down on the floor saying firmly but calmly 'no, I don't like that' and walk away. I think absenting yourself from her when she hits you will be sufficient for her to realise what she is doing isn't on and you aren't going to be her punchbag.
Good Luck
