my kid is having repeatedly mouth ulcer reason it's gives very pain and not able to eat

A. Dologel you can apply along with that give B complex supplement and start giving fennel seeds water because at the end of the day the tummy has to be really cool once you start giving that hopefully the tummy will be cool I’ll be easier for the child to get rid of the issue that is there please make sure to maintain proper hygiene and clean cleanliness with the utensil and the hands with which the child is eating
