Hello everyone hope you and dcs are all well .My dd who is three and who has autism was up yet again in the night vomiting .This is the sixth time since nov she's been vomiting .She has been off nursery as its the holidays and neither of my other two dcs has been sick . I am wondering if it could be lactose into.erence as we had mac n cheese for dinner and last time she was sick it was made worse by milk any advice would be most welcome .Thanks in advance
