oh what a decision! I had the same one to make before DS was born - had an hours commute, as did DH
I initially went for the taking the baby to work option, however I realised pretty quickly after DS arrived there was no way on earth I could do that to him. He hated being in the car and I can't stand a baby yelling for 5 minutes, never mind longer. He wouldnt sleep for the whole journey and the stress for both of us would be massive.
Um, then I resigned and now work from home!
Sorry that wasn't helpful was it - ok will try harder now.
My only advice is - try not to stress about it now because its not really a decision you can make until you meet your LO. And how they are in the car when they are born may be very different from when they are a bit older and more alert. You also don't know how you feel - you might desperately want to see them as soon as you can - or you might prefer to wind down after work and let them enjoy a bit more time at nursery.
By the time they are a few months old you will probably have a whole new network of friends and support that you don't currently have - I now have friends that I didn't know before DS was born, but whom I would trust completely to pick him up in an emergency if needs be (and only in an emergency - they have their own LO's to worry about!) More importantly - he knows them, so wouldnt be frightened. As I dont have family locally either this is such a wonderful thing - I met them all through baby groups - swimming, M&T, at the baby clinic, etc. My best friend I met at weightwatchers when trying to get rid of my baby fat!
Things will work themselves out. In the meantime, do your homework and check out all suitable nurseries both near home, and near work. There are also the childminder options - if you decided to leave the baby nearer hom e would you feel better if he/she were with a childminder who is perhaps more involved with your child, than in a nursery environment? Can you find out who will be available locally and meet them. you may find one you would feel 'happier' ( I know - wrong word) with in a situation where you couldnt get back quickly.
Good luck
