Number one rule listen to what she says. Why not take her out of the cart? But if you do you have to make sure to say "I will take you out when you behave like a person." As soon as she understand that she will listen it will take some time but she will get it. Or if she goes running down the aisle for example you catch her and put her in the cart for 5 min because she is 5 and explain to her why she is there so she is not confused on why she is there and after her time is up make her apologize. Now I'm gonna tell you something a lot of people don't agree with. Give her a spanking not a painful one, you don't want her to fear you, but if you do it early enough in life she won't remember it but she will later in life know to respect and listen to you. Beware there is such a thing as being to...how do I say this over parenting, if she doesn't know she did anything wrong give her a warning otherwise she will be afraid to do anything around you trust me I know my mother was like this. Best of luck and practice makes perfect it sounds corny but it is true it gets easier as she gets older.(at least lets hope)

Forget the bribery.

Take her back outside untill she straightens herself up and starts acting like a civil person.

She has to realize there are rules that she needs to follow.

There are far to many children falling out of carts that result in very serious injuries or death.

A lot of those accidents are because parents do not make their children sit down while in carts.

Sometimes it's not so bad to let the child walk along as long as they behave and don't drag everything down.

Sometimes a little treat is ok.

Try to teach her how to shop responsibly.

Good Luck.

I don't believe in corporal punishment. But I do think a really affective way to keep a child such as her under control is to take something she likes away such as a phone, toy, tv, ect. Tell her each time she acts up she loses the privilege. It's how I plan to raise my kid and how I've ALWAYS dealt with kids I were babysitting and always got a good review from the parents afterwords.

That's how all children are, tell her that if shes good that you would reward her with something she would like. Maybe a small ice cream or candy at the end of your shopping. But for the most part you just have to accept it to a certain extent.

She needs a time out. Even in a store you can put her in a corner. Watch Super Nanny for good ideas. You should take a parenting class.

It is best to take a child out to the car and let them sit quietly until they have themselves under control. If they find out that you are consistent each time they will learn very quickly that they listen or they are in the car till they stop.

You could like give her fake money when she is good. You put it in a little pocket thing. And when she is bad just take some of the money away. Then when she like reaches 10 dollars give her a prize. Or you could just give her an old fashioned spanking.

if she dose this all the time it best to leave her with a babysitter .When my son started to do what your sister I would just leave the store with him take him home and leave him with his father then go back to finish my shopping .But if you have to take her with you then before you go into the store have a talk with her inform her if she want to go with you she has to listen to what you say tell her if she can listen and show you she can be good you talk her for a ice cream or what ever she like just go through the drive through that way you wont have to have her screaming and kicking .

try rewarding her with stuff like cookies if she is good.

where are your parents?
