I have a similar commute and a baby, I'm working 5 days a week at the moment. At the moment I get her up in the morning, even on the days where DP will be at home with her, and it turns out we actually have about an hour before we need to leave. I do everything with her around - she plays in the bathroom, kitchin, living room etc while I shower and get ready. She's very cheerful in the morning so it is actually a nice time to be with her. I then see her for an hour in the evenings. She is still having a late afternoon nap which means she doesn't particularly want to be asleep until about 8, so as soon as I get home I take her, DP goes to get an hour to himself, and I do bathtime and bedtime.
Its not ideal, and obviously the whole work discussion is a much larger one that you possibly don't want to get in to here, but it isn't as bad as I thought it would be. I am looking on my commute, which is fortunately quite easy and so I can read and email, as 'my' time, which is more than I got when I was looking after DD. The weekends are great too, and I find I am a lot less frustrated by those little things babies do that can stress you when you are with them all day every day (refusing to sleep, throwing their food on the floor, taking 2 hours to eat dinner). I am happily busy in the evenings after work once DD is in bed so that I know my time is freer at the weekends to just concentrate on being with her.
One thing another MNetter said when I started a thread like this before going back to work was that whenever she misses her DC during the work day, she thinks about her DC having a lovely time playing at nursery/CM. I do that and it works. I focus on how happy DD is to see her CM in the morning and how obviously comfortable she is there. I focus on her getting to spend quality time with DP when he is looking after her.
Also, apparently it can take a few months to really get used to it so be gentle on yourself.
Lastly, if this is just how it has to be because of finances, long-term career etc., then always remember the Mumsnet mantra: it's just a phase. Another job may come along, a chance to work better hours may come along, the possibility of buying a house nearer may come along. Nothing is ever permanent, but sometimes you just have to cope with things being not entirely ideal.
