To find it mind boggling that people want to have more kids so they wont be alone in old age?

The children that is.
My sister and i harfly talk anyway.
Im undecided about another but i wouldnt factor in lonliness in old age. Aibu?

People claim that they are having kids for all kinds of silly reasons.

I suspect that mainly they just feel that they want them and then they make up reasons to try to rationalise those feelings.

The reasons are just something they can say out loud, because they don't want to say "I just want to".

I think if you have 2 DC there is probably a good chance that they could drift apart as they get older if they don't particularly connect. It depends.
We have 3 and even though they're all totally different (and don't always get on), they feel more "bound together" in a way because nobody wants to be the one left out in the dynamic! I think they will all support each other in later life, yes.

One of the reasons I want Ed more than one was so that he wouldn't feel overburdened by us as we got older but I never really considered his old age. Surely that's what marriage is for.

YANBU to think that.
I don't think it's a terrible reason though.
As an adult I find enormous value and comfort in being able to speak to any one of my brothers and have an immediate shared frame of reference. I don't see my brothers for years at a time. I often go months and months without speaking to them. But I can phone them at any time and say "Mum's opening a B&B" and they know EXACTLY what that means, why it's good, why it's bad, how bad exactly, if we need to do anything, who would be best to support Mum etc etc. I can think of lots of other examples. It's not vital, I suppose, but I appreciate it (far more than I did when I was a child with 4 siblings).

I reckon Trills is spot on: they are just trying to voice something that can't really be voiced.

Though as far as my own family is concerned it certainly looks promising:

MIL went into nursing home near my BIL; BIL & SIL visited her almost every day, dh and I and the children drove up as often as we could, especially towards the end, she had loving faces around her when she took a turn for the worse and eventually when she died. Her two sons may not have a lot in common but they have never fallen out and even the dividing of the inheritance was very amicable.

My own parents, now in their 80s, share a 2-family house with my db & family: they give each other freedom but are always on hand. They are visited every summer & Christmas by their other children & families. We all speak with them every week on the phone. And when there is an emergency, we four siblings keep in touch with each other. When one of them dies, we will be there for the other one.

My uncle & aunt moved to a granny flat next to my cousin when they became frail & elderly & the whole family pitched in to help them. When my aunt died, they were there for my uncle.

I have two DC and won't have another. I'd actually love them to have more siblings so they have more family and support when they get older. My parents died young and I have one sibling..we are a massive support to each other and I'd have loved to have more siblings!

Never I'm nc with my parents, my middle sibling is nc with our dad and my youngest sibling is nc with our mum (dysfunctional is an understatement).

I although I'm having more than one child in hope that they aren't lonely and have some family when we are no longer here. So I guess that falls into the same level of crazy as this lol. I watched a close family member struggle alone with their mums care and funeral and it just made me realise I really didn't want that to be just one persons responsibility.
