I always think it's interesting to check in at SiteMeter to see where readers come from and how people land here. Here are the most recent searches that have landed people here. Thought you might find this interesting.
"changing nappies at other peoples houses" (I love that word - "nappies"!)
"reasons not to have a kid"
"reasons not to have kids"
"Childfreedom" (lots of these)
"reasons for people to not have children"
"does anyone regret having children"
"I am regretting having children"
"100 reasons to have children" (the person who put this search term in then clicked on the post "The Top 101 Reasons Not to Have Kids - and Remain Childfree") - interesting.
