I dare not say what I think.  In the first place, does baby acne
actually occur at this age?  I haven't seen it, so I doubt the
diagnosis.  Secondly, if that is what it is, why would you ever stop
breastfeeding for something so trivial?  Thirdly, why would you treat
it?  I think this must be something else.

I suspect this dermatologist has run out of creative ideas
himself/herself.  The cream didn't work, so the problem must be
breastfeeding.  That's not a creative idea, that idea is as hackneyed as
they come, unfortunately.
