What about you make yourself a plan. Find out lactation consultant and ABA info, so you have a number in your phone if you run into trouble. Figure out what you could do differently this time (if anything). Figure out ways your DH and other support people can help. Maybe attend ABA things before the birth so you're armed with tips for troubleshooting and making things easier.
Then show the plan to your DH - he'll be able to see that you're serious about giving it a go, and if for some reason, even with all that support and preparation things go pear shaped, he'll be able to see you've given it your best shot and might be more supportive.

Don't forget it doesn't have to be all or nothing either. If things are tricky for some reason, some breastfeeds are better than none. All the best!
