• No evidence of infant failure to thrive, fever, or illness

Infant dyschezia
All of the following criteria are required:
• Healthy infant ≤9 months of age at the onset and cessation of symptoms
• At least 10 minutes straining and crying before successful or unsuccessful passage of soft stools
Functional constipation
At least 2 of the following criteria are required during a one-month period:
• ≤2 defecations per week
• History of excessive stool retention

• History of large-diameter stools
• Presence of a large fecal mass in the rectum
In toilet-trained children the following additional criteria may be used:
• Stool incontinence at least once a week
