L.P.
She sounds very smart and knows what she wants. When my daughter did this she was also about that age. She is testing you. I would try to distract with something she was allowed to do. If that wouldn't work I would put her for a time out in her crib until she calmed down. I would explain to her why it was wrong and then let her back out. I never had a problem with her going to be d in her crib for naps or at night. A lot of people do not beleive in time outs in the crib because then they think the child will associate the crib with punishment. I never had a problem. As my daughter was able to talk more she could express what she wanted and she had to get time outs less & less. I also give her choices so she feels independent. She is now 3 and she still has her tantrums occasionally but it is much less now. Children wnt what they want. That never stops.
