nkf, you have a point there. I do my agonising before the decision, but once the decision has been made, I rarely revisit the what-ifs, if things are going reasonably well.
For mostlymay who is on the cusp of going back to work or jacking it in, I would say because you can never know for sure what is the right decision before you have made it, choose the option that burns the least bridges. For me, that means keeping at least a toe in the workplace. If you go back to work and still feel unhappy about not seeing your baby enough or your baby does not settle in childcare, you are always tweak it. But it is far more difficult the other way round.
For me, because I really wanted flexible working, I negotiated something with my same company - not easy. If I left my company, even for a few months, I would have been stuffed. Before I became pregnant, the headhunters were ringing me all the time. The minute I mentioned I was only interested in a pt role, they melted away and never got back. The few roles they had that were pt were very poorly thoughtout and badly paid.
I don't buy it that dcs need you more when young. My dd 4.7 is starting to ask that I collect her from school (at 3 pm), rather than our aupair. She was really upset I did not watch her lunchtime ballet class. My ds 1.7 could not care less who picks him up from nursery. I understand that as children get older, more and more, only mummy (or daddy) will do.
If I really have to reduce my hours later on or give work up, at least I have that flexibility because our financial position is very strong due to dual incomes for a long time. This only came about because I took that initial risk and put my children in ft childcare to go back to work and the gamble paid off.
If I bought the line that children can only thrive in mother's care in the early years, I would never had taken that risk and possibly found myself pushed deeper into debt if I wanted to continue to stay at home when my dcs were schoolage.
