Summary and Recommendations
The choice of initial treatment with antibiotics or observation depends upon
the age of the child and the laterality and severity of illness:
• We recommend that children with AOM who are <6 months be treated with antibiotics
• We suggest that children with AOM who are between six months and two years be treated with antibiotics
