I have one DC and am pregnant with DC2.
My concern is that I am an only child, as is my DP (who is the father of both DCs), and my mum.
I think I have quite a romanticised notion of what it would be like to have a sibling, having always wanted one, but I read a lot about the complexities of some sibling relationships and a lot seems to stem from childhood and perceptions of favouritism or other inequalities in treatment.
Is anyone able to tell me what they wish their parents had known when raising siblings?
