Thanks ladies, thinking I was blind - I went to the centre and looked for a sign informing me of illnesses going around the centre - I couldn't find anything...

DD seemed better yesterday so I took her to the centre for the day - she wasn't sick, but only drank bottles. Last night we bought her home and she had part of a bottle and was sick all over DP. Then this morning I gave her part of a bottle, she was a little sick, but had diareaha (sic?) - and was sick again after that...so needless to say - it's another child carers leave day for me today...(should I thank DD for the long weekend?? )

So far she's had part of a bottle and hasn't been ill.

Thanks for the advice and well wishes in relation to DD - I may make an anon phone call about the lack of signage perhaps.
