I'm an only and always wished for a sibling. I still do tbh although my DM is now sixty seven so I think that ship has definitely sailed 🤣
However in the 80s and 90s being an only was definitely something of a rarity. I felt I was missing out on something that all of my friends had. A companion within the home, somebody to go on holiday with other than my DPs, a playmate and an extended social circle due to a sibling. These were things that all of my friends had and I was always very envious. Even now I am envious of my friends relationships with their siblings and nieces and nephews. This is mitigated nicely by my DH's family as he is the eldest of six so I do have a large number of BILs and SILs.
Altnough now that more people are choosing to have only children I think that there is less opportunity for them to feel as if they are missing out and surely they will feel less of a rarity as a proportion of their friends will essentially be in the same boat.
I know that my DM always felt very looked down upon for having an only, which is awful. She wished for more children but it just wasn't to be and says that other women often remarked that I would be lonely and psychologically maladapted (I am not)
I can't say that I would have chosen to be an only but I am very, very close to my mum.
It's a bit of a double edged sword tbh.
I would have liked to escape the UK years ago as would DH. How could I have done so as an only child whose dad had died in his fifties? I couldn't. It would have felt unspeakably cruel.
To that end I have stayed within half a mile of my mum because her health took a massive nose dive, presumably as the physical consequence of grief.
Now that she is almost seventy I am looking at extending the house so that she can live with us, because as an only what is the long term alternative?
And I do not begrudge caring for my mum in her later years. God only knows that she did the same for me.
And happily she and my DH get along famously.
Bit I've been very fortunate in almost every instance that these circumstances have and are seemingly going to work out well for us.
It's a lot to have on your shoulders as an only child. Sometimes when you are still relatively young yourself.
Yes, you can say that you wouldn't want to be a factor in your child's life choices, but if you have been a brilliant parent then necessarily that is what will happen because that child will love you to absolute pieces, Especially in the absence of an extended family.
Sorry for the essay.
There's plusses and minuses to being an only, no rights and wrongs.
I had a very privileged upbringing and I am forever grateful to the people who raised me, siblings notwithstanding.
