mouth thrush

HT

hi... my baby is turning 3 months this week and since his 4th week he has mouth thrush i have applied various gels on doctors prescription but nothing seems to work.... so i just read online that 1 ounce of distelled water containing grapefruit seed oil shall be applied on the affected area throughout the day this will clear up the thrush in a day or two....

has anyone tried it? shall i try it out or shall o continue the same useless oral gels
