On my sons recent 6 month appointment his doc filled us in on the following 9 month appointment. No shots but a blood draw. She mentioned it's done through the vein, I asked why not a prick and she said something about a bad reading. I can't imagine holding him down for this. Almost all my mom friends with kids have said their kids had a finger prick. What did yours say? Also if it matters we see a family practice doc not a pedi.
