I was at home until dd was 5. Then got a part-time job. That was 7 years ago.
At home: Immaculate house, every drawer tidy, nothing left undone, empty laundry basket every night, ran after school sports club, xmas fair and summer fairs, did reading at school with the children, helped make costumes for plays, went on school trips, treasurer of a local group, ran sunday school, vice chair of voluntary organisation. Decided I was doing so much for nothing and had so little time that I ought to be earning.
Part time: Immaculate house but drawers, etc., getting untidier, dropped helping at school, dropped voluntary work, dropped sunday school. Completely exhausting trying to do two things properly.
Full time work: Hire au-pair to sort out house, undertake professional quals (and get them). Children too old for au-pair, have a bit of help in the house, dh works away, on pcc, demanding job, older children as demanding as younger but different demands - can now drive 120 miles at weekends for matches, parties, etc, but have sensible conversations and go to toilet alone.
The future: Would love to be at home full time doing some things just for me but I have got used to financial independence. Also, I think I would just find other things to do so might as well be earning.
