In Training and I Need Some Help

JAC and I are currently in training. I'm not referring to our marathon training but instead sleep training. At our six month check up our pediatrician suggested it was time to start training JAC how to sleep through the night. The process is really pretty simple. When he wakes up in the middle of the night instead of feeding him I let him cry. I repeat this process for five nights and JAC should be trained. We are currently on night three and I'm about to fall over I'm so exhausted. JAC is an unusual kid and he definitely knows what he wants. He wants to eat. My refusal to feed him at three in the morning results in hours of screaming. I stumble in every fifteen minutes, stroke his head, give him his pacifier, assure him he won't die and cry out to God that my child will go to sleep. It is painful but supposedly in his best interest.

JAC is a little over six months old and I'm sure he's a little bored. I am admittedly not a "baby person." Part of me really looks forward to when JAC is older and we can play ball and do things that make sense to me. I need some help. What do you do with a six month old? Does anyone have any ideas for games that he might enjoy?
