The best advice I have and I think the hardest to take is to realize that you are going to have let some things go. That means that my house is never as clean and organzied as I would like, we eat a few too many take out/frozen foods during the week (even though they are organic its still too many for my liking!) and the laundry does pile up.
My husband and I really talked thru priorties in advance and we decided that for us a nanny would work best. This meant our son was home, had one on one care and took the pressure of the night time packing up for the daycare, the rush around in the AM getting everyone fed and dressed and into the car. And it allowed us to determine our own time off /vacations as opposed to working around a DCP. Having a person/people that you love and trust watching your child is the key to being able to go to work each day without any worries. If you are nervous about your girls you won't do anything well.
I also found it was very important to find away to decompress on the way home each day. Whether its great CD or a book on tape if you can mentally transfer yourself it will be much easier to walk in the door and not immeditaly think about dinner, the bills, the laundry etc. I spend the first 1/2 hour-45 min. at home just reconnecting with my son. He knows it "his time" and nothing gets in the way. No phone calls, no computer, nothing.
Its never easy but it does get easier! Somehow life just takes over and you just get into a rythmn. Good luck!!
