Congratulations on the birth of your boy!
I would suggest seeing another LC - sometimes it's really helpful to get a second (or even third) opinion, no matter how great the first LC is, as they all have slightly different experience and expertise and so may come up with different ideas. Have you called the ABA? They may have some advice for you also.

My letdown was painful to begin with but that improved with time, so hopefully that will get better. I think I also had vasospasm (self diagnosed, so don't know for sure) and those symptoms also improved with time.

All the best~~
