It was tough when we did it. Tough, but do-able.
I won't lie - if you are both working long hours / have long commutes, it is difficult. I did it for while and I suffered with a lot of guilt. Even with great childcare and support, it can be hard to be away from your child for most of the day, every day. Is there no way you could each negotiate an early finish one evening, or working from home half a day or whatever?
If you both have no other option, you will get through it. Good childcare, good organisation and a positive attitude will get you through!
You need a good nursery with 'wraparound care' hours (and take it from me...most children do eventually settle in and enjoy nursery) OR a good, local childminder (very close to home or on your way back from the station etc - it has to be an easy journey to make as you will be tired at the end of the day) OR...a good nanny.
If you can afford it, a nanny is a God send. Less hassly for all concerned. They can have your baby all snuggled up in PJs by the time you get home, and you can spend that quality time having cuddles, doing stories and bedtime etc, without all the 'grind' of another journey. And your child has the stability of being in their own home, with their own things around them.
My number one advice to you would be: think about what is going to be acceptable/easiest for YOU and your DH. Children are generally very flexible little beings, and if they have good childcare and a routine, they thrive.
