Welcome to Healthcaremagic. I am a pediatrician and am happy to help. Healthy breast-fed infants the age of your son pass between one and eight bowel movements per day with an average of two to four. They may have a stool after each feeding. The stools of breast-fed babies are pasty, mushy, and light yellow. Babies fed cow milk based formulas have one to four putty-like, firm, pale yellow stools a day. A viral gastrointestinal infection causes an infant to run a fever, vomit, have diarrhea, and a poor appetite. In any young infant who is having diarrhea with or without vomiting it is important to make sure they do not become dehydrated. Signs of dehydration include: no tears, dry lips and mouth, wetting fewer diapers that usual. For dehydration in an infant, ORS or Pedialyte are good choices. I hope this information is helpful to you. Please return if you have more questions. Arnold Zedd, MD, FAAP
