I’ve got a 3 year old DS and me and DP have decided not to have any more.
I had horrific PND and it was a really difficult time for us all. I still struggle now.
But I’m absolutely racked with this feeling of guilt, that I should be giving him a sibling because my body is able.
He saw his cousins yesterday and loved playing with them (unfortunately they don’t live nearby and were just visiting). I felt a sadness that he won’t ever have that.
I don’t want him to be lonely, but at the same time I don’t think I can go through it all again.
I had a brother growing up and my DP had a brother and sister, so neither of us know what it’s like to be an only child.
My friend who is older than me (I’m 33) and who had IVF to have her daughter is really upset that she can’t give her a sibling and seems to wish she was in the position to choose like I am…I feel terribly guilty 
AIBU to feel like this?
