My ideal would be both parents working part-time with the child(ren) going to nursery some of the time to get other influences and time with kids - especially important for only children - and mums (and dads) need a rest.
When my son starts school in September I will get some way towards this nirvana - with me doing a 4.5 day week, hubby doing a 4 day week (as 3 full days and 2 half days) so ds gets collected by us 3 afternoons a week and childminder 2 days a week.
I did think that his comments about the Danish nursery were somewhat flawed as from my experience, 18 months to 2 years was the time when my son didn't want me to go when I left him at nursery. He was fine up to then and fine after 2 (and was also fine 20 seconds after I had left the room from 18 months. So it was the worst age group to choose to comment on.
Anyway I don't see lots of disfunctional kids coming out of the countries where mums work and kids go to nurseries - in fact in other countries there isn't all this angst - why is it here? Why is parenthood so politicised in this country?
Also with this cortisol thing - has anyone looked at 5 year olds going to school and the stresses they endure? And what, as you get older, are you likely to remember - when you were 18 months old or when you were 5?
I do think the working vs on-working (mum - never dad is it?) is a non-debate - what really matters is that people can do what is right for them and that family life is supported fiscally so I completely support tax allowances against childcare (I'd like to see them against transport season tickets too mind you - completely off topic sorry) and I completely support transferable tax allowances between couples - should have been done yonks ago - it's only 5K you're transferring but I guess in most cases it's at the 40$ tax bracket so it would cost the govt a lot and then the childfree would be up in arms.
