Hi fairydust. Thanks for asking.
The pharmacist wouldn't sell us dactarin cos ds2 is so young. She said we should go to the GP first. So we tried the drop in GP near where we were on hols - but it was early closing day! The next night he was really disturbed, so we cut our holiday short and came home! We saw our GP, and got dactarin on scrip! Now he is much much better, and happier!
