Fandango I am in exactly the same situation! I am going back to work in Oct, 4 days per week. We live in a 2 bed at the moment but are in the process of busying a 3 bed in a nice area with good schools. Because I earn a decent wage, my partner, who works for himself, will be scaling downhis business to do most of the childcare.
I am very very happy that our DD will be with him, so I don't need to worry about her. But I am also jealous that my partner, being the lower earner, has the pleasure of looking after her when I will have to go out to work 4 days a week. If I earnt less, it would be the other way round!!
Of course, the choice is ours though. We could stay in our 2-bed and I could give up work, but we have aspirations and it is the best thing for our little family to have me working hard for another year or two, then having baby number 2, having good maternity leave and then possibly going back 2 days per week, or not at all.
Difficult though, I do feel for you.
