Of the three- pediatrician, LC, and the vacuum, only the vacuum helped! Changing input (changing the sounds, lighting, movement, location etc) are all excellent ways to comfort a fussy baby, and nursing baby is also a great- usually the best, comforting tool. Your baby is a baby and this is how babies this age behave. Also, I am afraid your vacuum is possibly better informed than pediatrician or LC.
Unless I am not understanding something, baby is behaving normally and gaining well. These behaviors you are describing is just how newborns are! Unless nursing hurts or something, there is no problem, and consequently, no interventions are needed. At all. No pacifier, no lengthening time between nursing sessions, and certainly not bottles. The paci and bottle might be nice for your convenience (although finger works just as well, really...as long as the finger is clean, fingers and knuckles are great temporary pacifiers when you cannot nurse- like when in the car for example.) But these are not in any sense medically necessary interventions. Pacifiers and bottles are pretty recent inventions, humanity survived and thrived for millennia without them, and both are only breast substitutes and nothing more. Your breasts appear to be doing the job so no substitutes required.
