#asktheexpert Hello Dr. Good Morning my daughter Rina is just 3.8 years old & she had some white patches in her mouth last week. We were concerned about the pediatrician he says it's a fungal infection & he suggested some liquid gel which we had to apply four times per day. she had fully recovered but after 2 or 3days it became little again I applied that gel again & it's gone. Again after 3 or 4 days it was yesterday we saw that infection in her mouth. plz suggest to me what it is actually. & what we have to do. last week when we visited the Dr. related to this illness he says rina has vitamin deficiency that's why she has this infection & he suggested the supplement of vitamins which we had to start from Sunday. Somehow we started it from Wednesday. Please reply to me. thank you.
