i got bursitis in my shoulder from holding my baby. i always held my kids on my left (non-dominant) side because i was doing stuff with my right while i walked around with them. i really recommend you try harder to switch sides, use a sling, use your hip more, something. i know its hard but shes just gonna get heavier. its been 6 years and mine still acts up, and i dont even use that side so much, i would imagine it would be even worse if it was my dominant side. see what the doc says.
