My husband rarely sees my kids either. He works from 1pm until midnight or later and is lucky to ever get even a day off a week. My oldest only sees him a few minutes in the morning on the way to school and maybe the one day off my husband is home. My youngest sees him right before he leaves to take my son to school and maybe a few minutes before he goes back to sleep or goes to work so she never sees him either. And we also have another one on the way. I dont think my kids have bonding problems but they are very attached to him and they tend to act up when he leaves or when he goes to bed because they miss him and dont see him much. Maybe try to talk to him about making a schedule for when hes not working. If hes home at night maybe see if he will take turns getting up with the baby every other time to feed or something or during the day have him feed the baby one or two times or something so he is spending time with the baby. Its not easy to make them want to I know because my husband always got frustrated when my kids were babies if I asked him to feed them or change a diaper or even just get up once a night with the baby but its always worth a shot. Regardless of how my husband feels I always try to get him to at least spend some time with the kids and right now were trying to create a schedule before the baby comes. Good luck
If the baby is a newborn, it is not surprising your husband feels this way. Men don't really bond that quickly with their kids, and they like them much more once the child learns to talk. If you are worried about the baby feeling close to the dad, ehh, don't worry about it for a while, the baby is too little to remember much about his life until he is older. If you're just getting a bit mad because your husband is not pitching in to give you a break, that's another issue, but it doesn't have to do with the baby bonding, it has to do with you wanting some equity in child care. Don't hit him with the bonding argument when you just want him to help out some.
