L., Check out last week's posting (4/2/07) from Dawn titled "4 year old acting out," for more input from moms. It sounds to me like your son is a good boy, but he's going through a tough stage like the rest of us with 4 year olds! The Lunchable was the thing that set him off that day, but he could have been tired or bored or frustrated and raring for a fight. Four year olds seem to be all about testing boundaries, and exerting their will, but they haven't mastered how to manage disappointment yet. You are right about it being difficult to discipline your son hours later. I think you and your mother should agree ahead of time how she should handle it when he's acting that way. I personally would not recommend leaving the store. Although it's embarassing, my thought is that my daughter doesn't want to be grocery shopping anyway. If she figures out that when she acts out, I'll leave the store, that'll just encourage her to cut my trips short in the future and I'll never get these kind of errands done. This principle DOES NOT apply to places that my daughter WANTS to go, like the park, McDonald's, a friend's house, etc. She knows that if behaves badly when she's playing, I will take her away. If we're in the store and she tantrums, I put her in the cart, put everything back that she had previously asked me for, and do my best to calmly continue shopping while she cries. You'll probably have a lot of well-meaning Grandma-types aproaching you, asking if your son would like a cookie, piece of candy, etc. When this has happened to me in the past, I have thanked them for their concern, but explained that my daughter was throwing a tantrum and I don't want to reward her behavior with treats. Again, it's embarrassing, but effective. If you tough through it a couple of times, he will quickly learn that you (or Grandma)is serious, and things like that will happen less frequently. Good luck!
