My kid is 4 years old for every ting she cry specially if I say no to her

I don't have kids but I think you have to stick to your guns you probably say no then turn around and give in that's why she keep doing it. My mom use to ignore me when I throw my body onto the floor in kmart. Eventually I get tired of doing that and give up.

Please explain your situation in further details so we can better reply to your question. What situations are happening. What are the rules of the house. What is your approach. We all can suggest things to make the situation better with more detail when you explain what has been happening. What has changed , etc...

I know she had a difficult 6 month's. I left my Husband and move in to my sisters home there she learn my sister kids manors and behavior on to cry for every thing I do to not give in to her demands it is hart I am along. So she what al ways to do her way. Because se leaned it from my sisters 11 year old

Ok, can you give more specific information. What "demands" what is she asking for that you are saying no.

What do you do now when she has a fit ?

A time out ? Penalty chair ?
A swat on the rear?

Gave her a smack on her bums exp if I say she must stop jumping on thes beds or she wants to play whit my comp or cell or she want sweets

Hold your guns and keep setting limits. Let her know bad behavior gets you nowhere. If time out doesn't work, try taking her favorite toy until she learns to cooperate. She's testing you because she is trying to figure out how far you will let her go. She is also more than likely adjusting to the new situation (although children are much more resilient than we adults)If you cannot control this situation now, it will only get worse as she gets older. I have found that as my daughter gets older giving her jobs around the house and allowing her to be a productive member of the family team helps keep these issues at bay (she is 5 now)
