How old is your LO? Time together on the train could be very difficult and more stressful than quality, if you get what I mean.

I also commute one hour each way. I bring a laptop with wireless internet. I get all my work emails answered, do a bit of shopping, browse some blogs, BB, etc etc, and generally relax and get all that stuff done on the train in either direction. It's a great "me" time even though I'm trapped on the train. I also buy a coffee at the train station cafe before I get on, and bring my sandwich breakfast, and it is soooo nice to eat and drink in peace . You can do your online grocery shopping during this time too, and do some meal planning if required. Pay bills, etc etc etc.
