Inquiring if a 3-month-old baby is suitable for consuming rice noodles.

A four-month-old baby can eat nutritious rice noodles, but it is recommended not to add too much sugar or just glucose. At the same time, you can introduce rice noodles and egg yolks, and take the baby outdoors more often to bask in the sun.

My baby, four months and seven days old, started eating rice noodles two months ago and then experienced constipation. After stopping the rice noodles, she now has bowel movements three to four times a day, a bit loose, and green in color. Is there any issue? Thank you! Additional question: What is meant by excluding infectious diarrhea? If it is indeed infectious diarrhea, what should be done?
