Objective: To define the bower habits of healthy Australian children a
ged up to 2 years. Methodology: One hundred and forty children were re
cruited in six age categories with a minimum of 20 children per catego
ry. Data on bowel habit was recorded by parents daily for 1 week. Resu
lts: Stool frequency decreased with age. Ninety-five per cent of infan
ts 0-14 days passed more than two stools per day compared with 21% at
age 13-24 months. Breastfed infants passed more frequent and looser st
ools than children fed infant formula and solids and also showed a wid
er variation in frequency. Conclusions: Mean stool frequency decreased
with age as did the variation. This is a combined effect of age and f
eed type. These data can be used as a guide to the bowel habit of heal
thy Australian children.
