Any good reads for new dads on breastfeeding?

I'm planning on BF and was wondering if you ladies had any suggestions on books for my husband to read to better prepare him for the reality of what this entails for me and us? Just don't know if he fully understands the scope of how much goes into the commitment of BF full time and would love for him to be as prepared as possible so he can in turn encourage me to keep at it when it gets tough. All tips or suggestions welcome thank you!
