Have been reading this thread with interest....
Lots of the 'pro child free' are missing the point(s) somewhat.
Weddings are expensive to attend as well as host (although as people have pounted out you can get married for under a hundred quid.)
Many people will be offended if an invitation to their wedding is declined, and lots of people (myself included who really doesn't like attending weddings) don't actually want to upset people they like/care about. Due to this my mother who herself lives 200 miles away and works full time is already 'booked' to babysit for two whole weekends so far this year and will probably have to give up a few more before the years out.
Also, again myself included, dont have easy access to child care at the weekends. I have no family locally and I am not comfortable to leave my DS with someone outside of my family.
Also, to be honest, if I am going to have a day/ night weekend 'off' then I would prefer to get away just myself and my DP, not attend a wedding, which as a previous poster or two has so eloquently put it is not about 'the guests' but about the bride and groom, end of story.
Hence geting invites to 'child free' weddings does cause a certain amount of difficulty and it also makes me sad.
Children are part of society and are our future (whether we all have them or not).
In other countries we would be laughed at for our uptight picture perfect ideas of what marriage is all about.
