Is it normal for toddlers to throw up in the night and for no apparent reason? My DD has been sick 3 times now and then is fine in between? she does not have diareah which I cannot spell. And is eating toast And marmite this morning. It was a bit frightening that she was sick all over her bed and I had no idea until she came in to me and smelt like vomit. I am also feeling guilty about leaving her as I am Working a lot - so perhaps I am overthinking...
