When my oldest had Rota 8 years ago he had d* AND v*ing on and off for a week. For days he's just have d* and then I'd think he was getting better and BOOM! he'd v*. With Rota MOST kids are lactose intolerant for up to a month. I've known more than one family who've had kids v* days after recovery because they drank milk or ate cheese. You might want to advise the mother that she may want to take that into account with this virus.

Regardless of what the kiddo has I don't think you need to worry. You're totally safe, I'm sure it's the same thing. Kids v* rather than have d*, they just do. I know that she had d*, but I'm guessing that his mom was starting to feed him normally (understandably) thinking that he was recovered and it was just too soon.
