I have never been especially maternal, and I put this down to being the oldest in a family with four children.
I love my siblings, but from my perspective, my parents having so many children ruined my life. There was no money, time, quiet, space - it was just chaos. My parents were very irresponsible and lazy, which meant I was often the 'third parent' to the youngest siblings, getting them up for school, making their school lunches, washing their hair etc when I was still a child myself. I even had people tell me I would make a good mother one day when I was about 12.
Any attention my parents had, when they could be bothered, would be directed at the youngest as I was 'more grown up'.
I found my siblings, and all younger children, irritating. The crying, the tantrums, the demands.
I do sometimes see children out and about and think yes, they're cute when they are well behaves. I think it would be nice to have family days out at farms etc like you see on Instagram, but then I see parents struggling with a child having a tantrum and I think how hard that life must be.
I do wonder if I will regret having no family but I think my childhood has scarred me too much. I feel resentful that I don't have 'normal' experiences as now I will be living an 'abnormal' life in the eyes of society.
