Gradual reintroduction of full-strength milk after acute gastroenteritis in children.

46 children (26 boys and 20 girls) admitted with mild acute gastroenteritis were randomly allocated to a regimen of continuing on full-strength milk, or to one of taking clear fluids until the diarrhoea settled before full-strength milk was reintroduced either immediately, or gradually in quarter-strength steps. There was no difference in length of hospital stay between the three groups.
