It makes me feel like an idiot, but I'm really not sure I know the difference. My guy sometimes spits up what looks like just milk and sometimes it's curdled... is that the difference? Or is it about how they respond to it, like vomiting is uncomfortable for them? I'm so clueless whenever the pediatrician asks me about this and her answer was, "vomit is vomit." But surely a not-yet-getting-solids baby's vomit looks different from my own, right?

So glamorous, this parenting thing.
