DS is 13 days old and started throwing up 2-3x/day about three days ago. It's different from regular spitting up - he kind of gags for a few seconds (for comparison, it looks and sounds similar to what a cat does before vomiting) and then throws up forcefully. He'll fuss for a few seconds and then seems unbothered.
Weight gain and diapers are great, he's generally content, and he doesn't have any other symptoms (at least yet) that would indicate pyloric stenosis.
Just wondering if anyone has experienced this before? Everything I'm reading about throwing up is pointing to pyloric stenosis but since he doesn't have any other symptoms, I'm not sure that's the issue.
