Stool with foam for a week. Past treatment and effectiveness: Haven't seen a doctor yet. What kind of help you want: Want you to give some suggestions and good methods

Doctor's answer:

According to the condition you purchased, the baby may have poor digestion... I suggest you take the baby to the hospital for a routine stool test. If it's caused by an infection, antibiotics need to be added. If it's indigestion, you can give the baby some probiotics.
