Consider the following

Leon is a Baby, My baby specifically. He is at this juncture 7 months old and 19 lbs, a good size baby for his age.
I was on a trip last week and didn't get to see him for almost five days. I had an urge to see him. An underlying desire behind my thoughts and whatever else I was doing.
When I finally got home he was asleep so I snuck in his room past his organic monkey and our snoring Dog. I was hurting just to look at him.

Yesterday I was playing with him and making him laugh and I realized that he doesn't do anything for me. I mean in a Utilitarian way. He provides none of my needs physically emotionally or otherwise. He is not capable of fulfilling me based on any of his actions. He is not even able to even comprehend that I am a being that has needs. He eats and sleeps for the majority of his day. The other small parts of his day are being held, playing on the floor or playing on one of his baby machines. I was on my bed and he wanted to eat one of my wife's silk pillows, The kind you have on your bed but don't use, just there to look at. Leon thought it might be a good snack and provided him a few moments of entertainment. I was looking at him there and I could feel almost a tangible Love for him. He wasn't doing anything for me. He was chewing on a pillow. I was only providing his needs (in that case pillow feeding) we were not in a reciprocal relationship of give and take. I made no contract with him. There was not a pre-birth agreement that if he follows certain guidlines I will be good to him.
I can't help but Love him. I can't help it. He hates being kissed. He does not like to snuggle. If you hold him he will look at other stuff. If you play with him he will scratch your face off. If you put your finger in his mouth (one of his great desires) he will chomp down on it with uncanny vice-like strength. He produces all other kinds of Baby fluids from multiple orafaces that all need to be cleaned and creamed. He wakes up at night and stays awake during the hours of our most sacred sunday afternoon nap. He tries to rip our dogs ear off and .... and.....and. I can't help but Love him, think about him, protect him and be a stepping stone for him.

I think that's how Dad's are supposed to be.
