Congrats to Brendan and Mary. They are pregnant. Welcome to the awesome world of children. A lot of people will offer a lot of advice. Some will make sense, some will not. You have to filter that and do what works for you. My two cents: Spend time with the kid. (I don't think you will have a problem with that). And assume that he/she understands, grasps, and can do more than you think he/she can. You will be amazed at the brilliance!!
Also, they are organizing the San Jacinto Endurance Ride: a self-supported mtb ride in the San Jacintos!! Sounds like fun.
Have a great day!!
