I've been wanting to say this for ages but hate getting involved in sahm/wahm debates. I hope it's okay to use your thread to say it, as you don't seem to want a bunfight!
Thing is, when people talk about previous generations, what they tend to mean is the last 100 years, and it's only in the last couple of generations that the 'mummy. daddy, children' unit has become the norm. Before the Victorian era you were either upper class - then other people looked after your kids, middle class (which was tiny then) then you had a maid and your extended family helped look after the kids, or working class then EVERYBODY worked including the older kids, and granny looked after the very small ones.
As a farmer's daughter back for generations upon generations, I can tell you that unless you owned the land, it was an exhausting, grinding, back-breaking way of life, which is why so many people flocked to the city with the industrial revolution - better paid, better chance of bettering yourself (though still rubbish for the very poor). The women had 10 kids, 3 of whom would die in infancy. They worked 14-18 hour days with no leisure time except going to church (which was people's social life then). they were worn out by 30-40. If your man died and you couldn't work the land, you and your children were out on their ear, thrown to the mercy of the parish. Those jolly yokels in paintings from the 1800s with their rosy cheeked wives and kids? They were working for the local landowner and at his mercy.
I think when we look back at 'people lovingly working the land', it's a gold-tinted view of the 1910-1950s. BUT the 1910s millions of men dies in the Great War, the 1920s were a period of major depression in the UK (The US had it in the 30s) 1930s and 1940s were marred by war and food shortages and it wasn't until the 1950s that life started to get better for everyone.
Trust me, from 1960s to now is the best era to be a woman and having children. We have choice - to stay at home or to work. Our children tend to live. If our partner leaves us/dies we no longer starve.
Enjoy your lovely baby, but don't wish up back in the past please - it sucked. Enjoy your choices 
Phew sorry, that was a bit polemical.
