Am I crazy?

We found out we were pregnant last year and my husbands parents were excited. A month later my husbands brother and his girlfriend announced that they were expecting. Now it seems like the parents ignore our child but fawn over their's.

They drive about 2 hours to go see the other baby but they say a 15 minute drive to see us is too far. They didn't come to see our son while he was in the hospital a few weeks ago but they drove 2 hours to see the other baby.

Am I crazy for not wanting to take my son there when they are going to treat him diffrently? Or am I over reacting?

My husband wants to keep going over there and I don't want to block them out of our son's life but I don't want to feel like it's a constant competition. My viewpoint is if they won't make the effort why should we?
