There are too many comments to comment on them all. If you repeat a specific question I will try to answer it. Many/most women find being at home deadly dull so don't do it. Simple as that. Vast numbers love their work. Many have a fantasy that being home with under 5 is lovely and then try it and realise it's very hard work for which you get little thanks.
Anyone who has small children whether they work or not know life is very hard in that stage. Hardest stage of my life was when we had a baby, a 1 year old and a 3 year old, whether you work or not but I would not have done it without also working as that would have been even harder.
On breastfeeding if 24 years ago I could work and breastfeed I am sure mothers today can do so although I didn't like expressing and when I had the twins and was mostly based working from home with email etc it was much much easier for the nanny to come in,s ay they needed a feed and then I'd go through and feed them at the same time. I have never bottle fed a baby personally and also my babies always just had my milk.
I would rather pay 41% upper rate of tax/national insurance than pay 60% + and have virtually free child care as might be the case if I were in say Finland or France.
Also being 46 with the older 3 children in their 20s now I do see the longer view, that the stage when they are little and hard work and you have no money does pass and that 20 years on you realise how much better we all are now because I worked, that that investment in the career which is never very easy in early stages whether you're male or female if you have children, pays off.
As for people taking a lot from a higher earning spouse on divorce although that is the law in practice many people do evade their responsibilities so it probably does pay most women to have some remaining earning capacity. Many a woman has to move on to state benefits after a divorce whilst the man has skipped the country with all their money.
I would much rather talk about the island as someone was asking. There's nothing on it except rain forest, bit of a beach, loads of birds on a bird colony, insects and I think I saw a snake. It's very beautiful and simple. I haven't built on it yet. We will probably camp on it next time we go. They do not cost huge sums actually. It sounds a richer thing to have than it actually is.
