I don’t often reply to posts on mumsnet but your post is one of the most interesting I have read and some of the obtuse replies have compelled me too.
It’s not hard to understand that as a child you took on face value your mum was home and sober, your house was clean and you had enough to eat and felt ‘better off’ compared to both your friends and especially those in wider society living in dire poverty. Those were your points of reference.
Then as you got older and fell pregnant young, combined with covid lockdowns, your world was necessarily small, you had nothing to compare it to except, often sensationalist, media headlines of poverty. You were clearly not in that situation, in that, though you had little, your children were loved, fed and clothed.
Now as the world opens and your children’s lives widen and include friends from more affluent and stable families you realise a gap.
I don’t think you have deluded yourself as much as your points of reference have changed and you are navigating a world you are new too. You were poor as a child - everyone you knew was poor, deprivation felt normal. It was the norm for you. In comparison to your friends’ lives, your’s felt secure.
Now you (due to children) have introduced new points of reference. More middle class, functioning and less chaotic families and you compare yourself to them. Your family’s life is secure (loved, warm, fed) but you note the material difference’s and it feels hard. It is confronting as the parameters you use to compare yourself to are widened.
You sound a nice woman, a nice mum and though it might be hard to see now, you are actually helping your children negotiate the transition through class structure. Your children won’t normalise chaotic, dysfunctional family life in the way you did as a child, because they likely won’t be exposed to it as much.
Your mum gave you the gift of a poor but stable home life. And you are giving your children the gift of a stable home life and the expectation of a functioning wider community.
I doubt anyone grows up remembering what socks they wore, especially if they were clean and not full of holes. However they will always benefit from a stable, loving home and normalised expectations as to what functioning family and community life looks like. You are giving that to your children and that is a huge accomplishment.
(Bed poverty is absolutely a thing and is often reported on.)
