8 day old baby wants to keep eating but throws up after

Ma

My son keeps wanting to feed every 10-30 minutes so I keep feeding him. But right after he vomits or spits up. Am I over feeding him? How when he keeps giving me insane hunger cues. I read online that newborns only went to eat if they’re actually hungry. Is this normal?? I hate that he keeps vomiting. It hurts me.
