Hi & welcome to YT. I would agree that this much vomiting isn't normal. Yellow bile vomiting sometimes happens when their stomachs are very empty. It is possible that your baby is having a reaction to something from vacation (perhaps he got bit by something). I would have him checked out by the vet, just in case. They can dehydrate with vomiting - so keep some Nutrical and/or Pedialyte on hand.
