@Rosebud1302 I've been thinking a lot about this today and I truly think that you and I do not have anything to feel guilty about. I think those that say it's "cruel" to "leave DS alone" truly don't understand how life works in much more than a general sense. There's so much more to it than that.
It's this I think, when a woman becomes a mum the wires in her brain get all tangled and her emotions and internal guilt-meter go on the blink even when it's unwarranted. Boy I wish I could undo that physiological change as I would be a lot happier!
I was just thinking to myself this morning "So I am thinking of having another child, going through the pregnancy, delivery, sleepless nights, possible debilitating PND again, breastfeeding, pumping, up the back blowouts, tantrums, bickering, crying, expense, teen angst, worrying what they're up to all hours of the night, university tuition, because this child and DD may or may not support each other when I'm dead and may very well hate each other and cause everyone's lives to be miserable? Sounds about right"
Had a good laugh, yes this subject causes me intense sadness/fear/angst but it is all a bit silly isn't it. I'd do anything for DD - literally. If a genie popped out and said "I'll ensure that DD has a happy, beautiful life if you jump off this cliff" I'd tip my hat and get a running start!
Truth is I can't bear to see DD brokenhearted and this sends my mum brain into crazy mode- but she WILL BE brokenhearted when we pass. It's the horrible price you pay for love. A sibling won't change the fact she'll be hurting and I think I am trying to overcompensate for that by thinking of giving her a sibling. It's just a mum's instinct to want to keep her DC(s) from pain but we can't can we. Hopefully by that time your DS and my DD will have families of their own - I think most people do go on to do this. IMO that negates any benefit of a sibling, and as it should be when a person marries or partners and has their own children, they come first and a sibling moves to the background anyway.
I think of my granddad's situation - he had one sister he grew up with, they were very close - she died in a car accident aged 68. Who do you turn to in order to grieve a sibling? And my nan helped him the most when his mother died 5 years later. I just say this to further illustrate there are no guarantees and the support of a spouse is often times more comforting than anything.
My DH has a sister and a brother - brother announced DC2 on the way in early December and they haven't talked since. He found out through the family that it's a boy. Would it be worth it to me if DD ended up having a relationship like that with her potential brother? I don't know. I can't see my DH and BIL ever being a great support to each other - they are cordial but not close.
It's my mum's 70th birthday tomorrow actually and this has been on my mind a lot, she has fewer years ahead of her than behind her. When she passes of course I'll be sad, but I'll lean on my DH and DD for support. I feel as ready as possible to handle it when that day comes as I have all the support I need right here. And at the end of my days I'll look back and smile knowing I couldn't have had a happier childhood and I did my very best to give DD the same, no matter what happens. I hope that, even if you don't feel this way now, you can smile and think the same thing about your upbringing and DS's as well. You're doing a wonderful job and you're doing everything right, please don't let outside influences tell you anything else.
