Newborn shoot away from Facebook

So my husband and I have decided to keep pictures of our son completely off and away from the internet and every social media outlet. 
However I'm noticing more and more that the photographer we chose for our maternity and newborn shoot is posting others baby pictures online.
Is there a polite way to ask not to do that with our child? I understand it's "marketing" and how she makes her business. 
Should I just ask that she not show pictures of his face? Help 😫 I don't want to be rude, but I don't want to let someone post our child's face online when we're not even letting family.
