My kids are *usually* well behaved in public.
My oldest is the instigator that causes 99% of the problems... so he doesn't get to go if he's not on his best behavior or his dad's not there to help. It's easier for me with 3 kids under 5 alone, then my 1 12 year old. LOL
Although, my 5 year old has had a couple of epic tantrums when I used the "wrong cart" a couple of times.
Did you know I ignored her, until she punched me and then I picked her up, dumped her in the cart, then stuck a 50lbs bag of dog food on her lap... and she was so shocked about the bag, she shut up.
Did you know that my 2 year old says "shut up" to people when he doesn't want people to talk? That's because my 5 and 12 year old fight and tell each other to shut up all the time.... and I didn't care enough to correct them, since they don't do it to other kids, just themselves....
Did you know my 2 year old will also stuff his fist in your mouth to shut you up if you ignore him?
Did you know I don't have much of that to worry about these days... But I'm the first one to smile and help a struggling mother in a store. I can't erase the tough moments of having young ones in my head.
