I have just been reading this topic for the first time and am a bit concerned that it seems most people are unhappy with their only child status. For a long time I felt the same way, but it was not to be...IVF failed a number of times and I just gave up the ghost after a while. For a long time I felt somehow inferior to my friends with more than one child...combined with guilt for not providing a sibling for dd, that was not a good place to be.
Now, however, I really can appreciate how brilliant an only child can be. DD and I are so incredibly close. We do loads of things together and sometimes break down in giggles together at some stupid thing or other. Her schoolfriends mostly tell her how lucky she is not to have an annoying brother/sister. We don't get any sibling rivalry/arguments and can go out for dinner pretty much anywhere. Trips away can be organised pretty easily, as can babysitters as people like hanging out with dd (who is nearly 9).
My sister and I are fostering the relationship between our only daughters so that one day hopefully they will have the familial support they might have got from siblings. Remember siblings DO NOT automatically get on because they are siblings. I know many people who have nothing to do with their brothers and sisters because they really do not like them.
One is not ideal..I am the first to admit that I would have liked another, but it was not to be so I thank mylucky stars that I was given this gorgeous, funny girl.
For anyone that is struggling with the only child, try and remember this. Plus: only children are the new black! I know at least 5 other onlys and they are increaing at a rate so it is not so unusual anymore.
