I am one of those ‘don’t like children’ people. But that is mainly in response to queries from nosy buggers asking why OH and I don’t have any children of our own (he has one from a previous marriage). What I really mean is:
“I love tiny squidgy babies, even when they are crying. I like fat nappy bottomed toddlers. I like kids when they get to the age of about 13 and you can have a proper conversation with them. I’m not too fussed on kids between the age of about 3 and 13 as I mostly find them highly irritating. However within that age bracket, I do know quite a few children that I do like, but they are the exception rather than the rule, and on the whole, I prefer my time to be free of screaming, whinging, mess, tantrums, cartoons, loom bands and ‘I want’. This is why I don’t have children of my own, because there are about 10 years of parenthood that I suspect would drive me absolutely insane, and that I wouldn’t actually be a very good mother.
On top of that I am not actually convinced that I could conceive given my age and previous gynaecological problems, and I’m not about to put me and OH through IVF or anything similar for something that I’m not 100% sure that I really want. I do regret not having had children when I was much younger, now that I see a lot of my schoolfriends waving theirs off to Uni and generally enjoying their teenagers as semi-adults, it makes me sad that I don’t have that. But I wasn’t with the right man at the right time, and now I am with the right man, it’s probably the wrong time given where I am in my life.”
But instead of saying all of that I generally just say ‘it’s not for me’, and then when someone presses the point and wants to know why (which they generally do), I say ‘I just don’t really like kids that much’. It’s easier, and it’s no-one’s business other than mine why I don't have / want children.
