Oh I love time away with my dh, absolutely, we had 4 nights together in hotels without children last year. But I think (personally, just me, realise not everyone agrees etc etc) that weddings are family occasions and therefore children are not at all out of place, in fact bring lots of lovely things to a wedding. Which is, after all, the joining of a woman and man and may well result in children. So I think a wedding is not a party, it's a family occasion and my children are part of my family. Yes, I'm pleased to be invited to a wedding (or anything, quite frankly) but I wouldn't really want to use my precious overnight babysitting on going to one. Not that it matters now since most of my friends are either already married, divorced, about to get divorced or on their second marriages and have children themselves so wouldn't send a child free invite. So this doesn't figure irl for me at all!
And we got married in 2005 and had nearly as many children as adults there, it was lovely.
