I knew about the baby, but I didn't know you hadit's father. Did you go back and get him? Or do youmean bonding him to an older male, ie Jack?
Check out the sticky at the top of the forum. There are somegood links on bonding. Have you been introducing them in aneutral area? The older bun may feel like he needs to defendhis territory from the newbie. Try letting them get used toeach others' scent first, then introduce them in a place where neitherhave ever been before. I've heard of using bathtubs and carsfor this in a pinch, also large table tops if multiple peoplecan help out.
