I know this is a very emotive subject on MN so, donning hard hat, I would say that I would agree with them CQ.
However, obviously special dispensation for breastfeeding mothers or mothers of newborns. Also don't know if it makes a difference with age of children - eg. I have only taken dd to one wedding and she was 18 months and dh and I spent the whole time chasing after her around the hotel then had to trust the hotel listening service once we'd put her to bed (which we didn't so we ended up going to bed early). I think we'd all have been happier leaving her with grandparents for the weekend but then we have that luxury which lots of people don't.
