Please do not give Montair LC Kid to your 10-month-old baby without a direct prescription from a paediatrician. This combination of Montelukast and Levocetirizine is generally not recommended for infants under 2 years of age due to potential side effects and lack of safety data for this age group. A 6-day runny nose is common and usually viral. Instead, you can safely use pediatric saline nasal drops (1-2 drops in each nostril) to clear her nasal passage and keep her well-hydrated. Please consult your paediatrician for a proper physical examination and a safe, weight-appropriate treatment plan.
