Thanks for your query,
Upper respiratory infection
is usually recurrent in toddlers due to decrease immunity.
is viral of bacterial in nature and takes few days to settle.
Relax,continue with medication as prescribed by your doctor.
Noisy breathing persist fir sometime as little child cannot expectorate sputum so he swallows and in few days he passes it in stools.
Give plenty of lukewarm fluid,give steam inhalation.
Wishing your child good health.
