HFMD affects the oral cavity for children with herpes or ulcers in the oral cavity, which can be painful, and children are reluctant to eat. The diet should be easily absorbed, avoiding spicy and sweet and sour foods, and not eating fried and greasy foods, as they will increase the burden on the gastrointestinal tract. For small babies, you should also pay attention to personal hygiene, wash your hands and rinse your mouth more often to promote the early recovery of ulcers, and your diet will be able to return to normal as soon as possible.
