It is daktarin oral gel, 2%.
Lady in the chemist said to use it four times a day after looking at DD's tounge/mouth and asking her age (4yo)
Weve been using it since saturday morning and ive just checked the leaflet and it says to use only twice a day for children of DD's age!!!!! 
I did read the leaflet before but missed this bit, only saw the 4 times a day for adult/elderly!!!
at myself!!
Will this have harmed DD? I feel awful :(
