What are the symptoms of mouth ulcers in newborns?

Patient's question:

The child just born doesn't know what's going on, there are always red spots on their body, and they are also spitting up milk. Please ask what are the symptoms of mouth ulcers in newborns

Doctor's answer:

Generally, use a 5% sodium bicarbonate solution diluted 3 times, then rinse the child's mouth, 5 times a day. Additionally, apply Tinling Powder to the child's mouth, which is very effective. Most of the time, it will disappear within two days.
2. If the above method does not work, you may need to use Nystatin Mouth Drops. This medication can cause liver damage, so do not use it unless absolutely necessary.
Your condition may be caused by calcium deficiency. It is recommended to supplement with calcium. Yogurt is also an excellent calcium-rich food. It not only provides calcium but also helps regulate intestinal function due to its beneficial bacteria, making it suitable for all age groups.
