...as well as entertaining reading
Sometimes, though, parents are trying the OTHER approach to temper tantrums -- SOME kids (my oldest dd, when she was younger) will take the power they get from causing you to leave somewhere and RUUUUNNNNNNN
with it! Then, forever after (or it seems like it), every time you take that child somewhere they would rather not be, they have the fit again. Flame away, I took her to several psychologists for years in the attempt to find a discipline method for her.
BUT, that said, that is a 3 yr old having a temper tantrum. In a restaurant, with this type of child (my dd), I would walk her to the bathroom (or the parking lot, whatever!) and have "time out." Away from diners. If my child was just running around, climbing tables, etc, that is different -- that child might need a different form of discipline.
I just wanted to throw out there the possibility that a particular child might not be the one to take out and leave. Some kids even need their tantrums to be completely ignored. No reaction whatsoever. We are doing that with our 6 yr old who cries LOUDLY and DRAMATICALLY about everything. But no, I would not ignore it in a restaurant, lol.
That said, we always take our kids to restaurants -- all kinds. We get tons of compliments about their amazing behavior. But *G A S P* even MY "angels"

have had moments, and 1x in a store I overheard one employee say to another "Why do people have kids if they can't CONTROL them?" Those employees had no idea that the misbehavior (severe bickering btw 3 and 4 yo) was a complete fluke, even shocking me. So just so you all know, my kids, as great as they are in restaurants, will not be partaking of fine dining at WDW this year. I just don't know that they will all four behave on that particular day, at that particular meal, lol.
Just was chiming in to ramble, and let you all know that opinions, whether I agree with them or not, DO matter to me!
