Oh, for heaven's sake. This is what's wrong with society today. G-d forbid should we do something that might be difficult for the child. My husband and I went, test drove and bought a car with our 3 year old and 4 month old in tow. They lived. My 3 year old may not have wanted to be there, but tough. That's life. If the OP doesn't like her MIL, then she needs to figure out life without MIL's help. And sometimes it might mean incoveniencing her child. The horror. Boredom never killed a kid.
Wow, so not taking a child to a car dealership to spend hours exposed to God only knows what kinds of germs and dirts is what is wrong with society?? Seriously, I think you just got a little over dramatic. Oh and do you know how many kids die from RSV or have life long health problems from it?? Taking an already sick child out puts them at a higher risk especially if they are 2 and under.
This thread just has me laughing at the responses from some people. Yes, the OP needs to find someone else but is your nasty remarks and "I'm better than you" comments really necessary??
