My 7 month old DS had a horrible tummy bug which lasted most of last week. He had vomiting and diarrhea and was generally unwell. He has been much better this week, I would say 100% apart from the fact that every 2 or 3 days he projectile vomits as though he still has the bug and is then fine again. I asked the health visitor about this and she said it's completely normal as he still has a tiny bit of the virus in his tummy but how long will it go on for?? Does anyone else have any experience of this? Help!
