Saline nasal drops or sprays with a concentration of 0.65% sodium chloride are generally considered safe for young children, including toddlers around 20 months old. These solutions help to moisten nasal passages and can relieve congestion without the use of medications.

Key points to consider:

• Safety: Saline nasal drops are non-medicated and typically safe for infants and toddlers.
• Usage: They can be used to clear nasal mucus, especially during colds or allergies.
• Concentration: The 0.65% sodium chloride concentration is mild and suitable for young children.
• Precautions: Always use as directed, avoid contamination of the dropper or spray tip, and consult a pediatrician if symptoms persist or worsen.

If you have any concerns or if your child has underlying health conditions, it’s best to check with your pediatrician before starting any new treatment.
