It is normal for children to test the boundaries that you are putting in front of her. Believe me I know because I have a 2 1/2 year old and a 18 month old. I tell them that they are being naughty, and if they do not stop acting out then I will put them in their bed or room for a couple of minutes. I tell them that when they can behave appropriately then they are welcome to join us. Since I have been removing them from the area where they are acting out at, they have been changing their attitude, and the incidents have been fewer and farther apart. I hope that this can help you some. Good luck!
