Paddington,
I'm the father of three young children (of course) and losing that second income (our choice) was a bloody nightmare so I understand your predicament. We made a lot of sacrifices, and I'm not just talking about changing to Tesco's wine. In the end though we did what we thought was best for the baby and that was (for the first eighteen months at least) to have its mother there 24/7.
I personally think that its a sad indictment of our society where this is now considered negotiable for the sake of a career.
Ok, that sounded really holier that thou and I apologise because you'll have worked bloody hard to get where you are, but you should prepare yourself for the reality that (depending on the bond you form with your child) when you hold that brand new life (that you made) in you arms, EVERYTHING will change.
Good luck and I hope it all works out
