Scrap that, I do feel sorry for your kids. It's not so much for the fact that you live so frugally, (if for eg you were really poor and framed the post as such you'd have had different replies!) It's more that you think your very extreme way of living is normal and makes you morally superior to all those wasteful folk
It doesn't. And I'm sorry but I think if you have the money to do so, then spend it however you choose. I mainly use Lush products for the shower, in fact I went there today and bought two small bottles that I don't strictly need (I have two on the go at home) however one fragrance (American cream) had ran out and besides which I like using different shower gels on different days. At home we always had imperial leather shower gel which was ok, bit the special shops were too pricy in mams eyes. So that's a little luxury I give myself. So is buying a room fragrance spray from next that smells lovely, as opposed to trying to do one myself.
I agree that cutting down on waste is a good idea, recycling, donating to charity boxes. That said, if I want to spend my hard earned cash on shower gels, new boots, nice holidays, etc etc, then I will.
And I imagine a 'materialistic' lifestyle (I hate that term actually, as though it is awfully wasteful, and a crime to enjoy your money. It's perfectly ok for people to enjoy life otherwise it's bloody miserable) is less damaging to children than the extreme lifestyle you list. Your dd will be a prime target for bullies as she gets older.
How will she feel when she knows her friends all spend weekends going to the cinema, parks, shopping malls, etc and she has none of that?
How will she feel wearing brothers hand me downs at age 11ish when other girls are starting to develop their own taste and wear bright jeans etc?
When everyone's discussing going to nandos after school and discussing what they'll have and your dd not joining the discussion because she's never been and doesn't know what they serve? Or even worse not being able to go due to it costing more than a fiver.
Most teenage girls (in fact most people I know!) Prefer shower gel to soap. I always have, for example. You get a better lather off it. I also imagine you're not buying interesting smells. So again when she's in school or with her Mayes and they're discussing which lush / body shop etc product they like best, she will feel left out.
I'm sorry but unless it's a life of necessity (in which case I hope things improve in your future) I actually think you're disadvantaging your dd. imagine living a life where all you get is hand me downs from a relative of a different gender, where your clothes don't smell of comfort like others, where you never eat out, where you have no say in shower gel or soap, where you wear clothes much bigger than your actual size (one size bigger is fine especially for really young children but anything more looks ridiculous), where cruelty to animals is normalised (I'm quite afraid of birds after a terrifying incident with a seagull when small but I don't go chasing them. Except when I was 18months and my parents soon got me back). Where you never do the same activities as your friends, where you eat sardine pizza, where you burn I'm August due to fake suncream.
That doesn't sound a happy existence does it? It's certainly nothing to be superior over
