Sounds, like you are a new parent. As a child grows many things are consumed that can potentialy harm him/her. Although, the though the thought is gross, dont panic. keep a close watch on the baby, if the child starts to show signs of sickness take him to the doctor, and let the doctor, treat the baby. While flys can cause heath issues, often the only adverse occurence is the after thought of a parent. Thank You (hang in there)
