First...don't stress! Stress can lead to other issues with BF! It sounds like you're doing great.
As for the strong let down....I always had one side that was like that as well. What I would do is put my wrist across my breast where I knew the let down occurred. This allowed to slow the let down some what as to not choke my DS. If DS was on the other breast, I would still have my wrist on the strong let down breast to keep me from leaking everywhere.
If your LO is gaining weight and the DR's don't seem concerned, then you shouldn't be either. He wouldn't sleep wel if he was hungry, he'd probably be a very crankky LO if he was hungry.
LO's at this age are still needing the sucking to help calm them, so him taking the paci doesn't mean that he is hungry. Are you feeding every 2-3 hours? If so, then I would say you're doing fine with the feedings. He could also be a really quick eater. Once my DS got the hang of BFing, he would be done so quick!
Some signs that DS acquired to show that he was hungry was being fussy, rooting (almost like a pig) against my shoulder, or if I questioned his hunger, I would hold him int he cradle position against my breast. If he went for the breast, then we would nurse. We weren't on a strict schedule at 7 weeks.
HTH!
