My mum worked FT teaching, my dad a HT. I was looked after by a childminder from 3 months old. I think she might have wanted to SAH a bit longer but they'd been married for 10 years before having us and had finally bought the much desired detached house just before mortgage rates went up. 
My abiding memory of primary school years was always being the last in the playground to be picked up. I went in the taxi service as an 'act of grace' passenger - when it was my brother's turn to go to school, there was no room so he got to travel to and from school with my mum and went to a completely different primary. A lady down the road used to wait with me in the morning before school and I went to her house after school too.
I don't remember them ever attending sports days, special assemblies, afternoon nativity plays... as a younger teen I took myself off to all medical/dental appointments after school and she met me afterwards.
The only topic over teatime was the kids at their respective schools. It struck me that they were more invested in their lives and education than that of their own children. I was a very secretive teen, with a wild social life - they provided the odd lift!
My mother sacrificed absolutely nothing to have children- in fact I really do think they eventually got round to having us because they felt they ought to, not because they particularly wanted to.
That said, I admire the work ethic! I've done a bit of everything. Went back F/T when eldest was 13 months which was horrid but had a high earning 'partner' who didn't share his earnings. Was a single mother on benefits for a few years when eldest was 2.5 - 4. Yes, that was a conscious decision because she was so traumatised by the DV I suffered at the hands of her father, combined with me not being around enough for her that she was absolutely feral and didn't speak a word of English!
When I moved in with lovely DH and eldest went to school I did a part time school hours waitressing job until having DC2. Was a SAHM for 3 years then did a few evenings and weekend pub shifts. DH very hands on with the kids and encouraged me.
I think we've got a good balance now. I'm in a job that is p/t, low paid but quite high pressured (NHS primary care) and feel like I'm doing something useful. DH works mostly from home, does his fair share of school runs and evenings with the kids when I'm on a late but I'm around a lot for them and manage to attend all their school events.
I must admit that I do work with someone who has been out of the workplace for 20 years and it really shows - I think it is useful to keep doing something while the children are school age, even if you don't necessarily have to.
I do envy the clean and tidy houses of my SAHM friends though!
