Indeed. When I was pregnant with my first, I read loads of articles based on psychological studies about the impact of childcare on babies. The vast majority were in agreement - the quality of attachment to the the main care giver (usually the mother) is the single most important denominator, alongside the quality of the childcare.
I was fortunate, in that I was in a decent(ish) job that meant i was able to save in order to bolster SMP, and i was in the public sector where enhanced maternity pay is good. I therefore took off 9 months, but had to return full time - partly because flexible working back then was not as good back then (they almost certainly would have refused part time hours) and partly because I didn't want my career progress to stagnate. I don't believe there is anything wrong with a woman ensuring she can be financially independent should the worst happen - in fact, it's incredibly sensible. Too often, I have seen women sacrifice their careers, only to find themselves in dire straits when their marriages/ partnerships fail. Then all the children remember is the struggles mum (usually) faced, the fact that there wasn't enough money and mum was constantly stressed out and didn't seem to enjoy their childhoods.
Once we had weighed up all the options, we actually chose a really amazing childminder who has remained with both our children - our ds until he went to secondary school, our dd (8) is still going. By the time our dd came along, I was in quite a senior position which afforded more flexibility and I dropped to 4 days a week. Childminders are often overlooked, for a variety of reasons, and don't suit every family. But when you find an excellent one, they're worth their weight in gold. The homely environment suits a lot of children, and they often get a chance to build a strong attachment to their childminder, as well as their parents - which psychologically speaking is really healthy for them. They get loads of one to one due to smaller group size and are able to have more quiet time if overwhelmed. Our cm is like more of an antie to our dc, and a friend to us. My ds (14) still drops in to see her and give her a hug on his way to/ from school.
The quality and affordability of childcare and maternity/ paternity leave and pay (across the board, not just for higher earners) is what we should be talking about. Not 'women furthering their careers at the expense of their children' which is merely another stick to beat women with (where are the men in this equation?) when motherhood is already fraught with judgement, shame and guilt.
