I was doing mums hair the other day (she's 82) and said, "i'd spend more time with you girls, if I could have my time over".
We had (I think) a good childhood and according to today's standards, we lived in poverty! No double glazing or central heating (neither came until the 1990's and I'm the youngest born in 1974). We were healthy though, frost on inside of Windows never mind outside! Once a week baths as long as the fire got the water hot enough!
Walked to school every day, we're rural, school is town, old scrappy bikes that we'd go off on long bike rides around the country lanes (I won't even drive those country lanes these days as folk stick to 60mph mentality!!)
Mum was a farmer and worked from age 14 and she and dad split when i was 3 (probably because I have no memory of them together is the reason why I won't take crap off him, I'll stand up to him, he doesn't like it and will sulk!).
So mum brought us up single handed on hardly any money and worked a hard physical job whilst keeping us 4 fed and warm (£20 a week off dad didn't help much neither did the child benefit off the state for 4 children).
She helped my sister by being a full time carer to her 1st grandchild 30 years ago but then realised when the 2nd one came, she couldn't do it (well done to all of you who look after your grandchildren!!)
Mum worked and has said many times, she worked because she HAD to and knowing how much debt she was left in (not her fault either) I can understand it. Only now, when she's at the stage she is of her life, she has regrets!
I think if ANY mum CAN afford (without state help) to stay at home and be a full time mum then do it, but not if the taxpayer is going to have to foot the bill. My niece has an almost 3 year old and says money wise, they can afford a 2nd or her to stay at home, but she doesn't want to do either as she loves her job and she says family dynamics at the moment are perfect, mum, dad, kid & dog! That and they have a caravan and go On holiday frequently in it!
