I think that there is a huge yawning gap in all these debates on going back to work, and that is financial incentive/control over work.
If I could earn 10 times as much as my nanny and domestic help, and be sure that I can pick the absolute best, trust them to form an attachment to the baby, structure my working day around expressing breast milk. If I enjoyed work and found it so stimulating that I couldn't bear to be away from it.
If working made a huge difference to my finances, and took me from living in a flat with local state school provision etc etc to living in a mansion, with a cleaner, the pick of private schools etc.
If I was reluctant to lose the job that provided me with all these priveleges, then it is possible that I would consider going back to work at 2 weeks.
As it is, I would be searching around for a local childminder prepared to look after a 2 week old, while they looked after a host of other children of different ages, doing countless other school runs etc., with no way for me to check their track record (other than Ofsted registration).
I would be doing this to make a marginal difference to my standard of living. The difference between stat maternity pay and my salary is significant, but not a life changing incentive to go back before I absolutely have to.
If, on the other hand, my salary was so low that it made no economic sense to go back to work, to basically cover the childcare costs or not even that. If my husband earned enough to support the family comfortably, not just in the short term, but to give us long term options.
I believe that all of these reasons are behind the real decision faced by women. SAHM does not equal "earth mother". WOHM does not equal "heartless b*tch who should never have had children".
The choice is much starker for many of us. We cannot follow instinct, but allow head to rule heart. And if Xenia's posts provide consolation to any of us like that, then I am all for it.
