Breastfeeding support for dads

My wife is breastfeeding and I feel kind of useless honestly. She's doing all the feeding and I'm trying to help by doing diapers and holding the baby after, but I feel like I'm not bonding with him the same way. Plus I see her struggling with latching issues and I can't really fix it. Any other dads feel this way? What did you do to feel more involved in the feeding process? I keep thinking about suggesting formula so I can help feed him but I don't want to pressure her if she wants to continue nursing.
