Just thought about this and decided to post it, it might help someone.
Gt a webcam and get your parents one too. Then video skype / AOL ichat them. Easiest way is to buy Macs as they have them built in or stick one on your PC.
They get to see the grandchild without a 2hour drive and you get someone to talk to who wants to hear about how the baby slept last night. For some reason video calling is more relaxed than chatting on the phone.
Plus you might be surprised how much closer you get to your mum when you have a baby. It changes the dynamic.
Anyway - it's working for us for my parents and the inlaws. No guilt about not seeing them every other weekend.
