My friend does this to her child too, and I just watch and shake my head. Why WOULDN'T your child keep doing this, when you chase after her each time? Kids LOVE to be chased, and those kids that you see running through the stores with their parents not far behind chasing and screaming after them are completely in a role reversal crisis. Let's not ever forget who's in control in a parent/child relationship. My friend's child COMPLETELY controls her, and she just turned 3!!! My kids would NEVER run away from me, but if they ever did, I would stop in my tracks, and stare at them with "the look". If they kept running, I would say "okay, Aryana (my daughter)! I'm going to keep shopping! We'll see you later!" Now the first time you do this, chances are your child will not fall for it for awhile. But, make sure that the first time you attempt this, you go to a store that is specifically for the purpose of putting an end to the behavior. Go to a Walgreens, talk to the cashier at the front of the store, tell them what you're going to do and say "If you see her coming this way, please call me over the speaker" I'm not kidding, it's down right dangerous for you to allow this behavior to continue. What if you were chasing after her, slipped and fell while she continued to run, and someone grabs her and takes off with her while you're down? It's not just a nuisance, you're putting both of you in danger every time you allow it! So, back to the intervention part. A better idea would be to go into a small store like a Walgreens, bring your husband or mother or someone with you to stand at the door to leave. Let your child down and if she starts running away, saying "Bye, Aryana, mommy's here to shop not chase you" and literally walk the other way. Children freak out when they see they're mommy's not close to them, and your child will eventually stop the running. Let her run for as long as it takes the first few times she runs away because you have her trained right now to think "If I run, mom will chase me". So, she's going to run for quite a while, waiting for you to chase her. Once she realizes you really may not be coming after her, she will come back. Then the next time, she'll run a little less far before she comes back. Then, even less far before she realizes it. Eventually, she'll give up on it and WANT to stay with you. I would imagine you refer to her as a "strong willed child"? That's what my friend does, and I always say "no, she's a child who's allowed to be strong willed"
