Thank you all so much..I feel alot better. My usual GP said he wouldnt give it to her because of her age..I was thinking she was too young but obviously is is the point she is too old for the original course at 12 weeks.
I'm sure it was the serum now, and because it was diagnosed when she was in hospital with a stool sample they knew it was rotavirus she was exposed to it then.
Well I have learnt alot today and thankfully she is still her usual self
