1, find the ulcer site:

When there is an ulcer in the baby's mouth, carefully observe the baby's mouth and find the specific part of the ulcer. If the ulcer is in the buccal mucosa, it is necessary to further find out the cause of the ulcer: for example, see if there is a sharp and unsmooth gap in the teeth near the affected area. If there is such a gap, you should take the baby to the hospital for treatment.

2, diet analgesia:

Don't give your baby sour, spicy or salty food, or your baby's ulcer will be more painful. The baby should be given liquid food to relieve the pain and help the healing of the ulcer.

3, divert attention:

Pay more attention to the baby, talk with the baby more, divert his attention, and create a relaxed and happy living environment for the baby.
