Hydration for all infants
It is reasonable to not perform continuous oximetry on infants and children with<unk> O2 (maintain SaO2 >90%)
oxygen saturation alone should not dictate admission

There is insufficient data to make an evidence-based recommendation about suctioning.
Nasopharyngeal suctioning may temporarily relieve symptoms
The use of routine “deep” suctioning may lead to increased length of stay based on one small study 
AAP recommends as a possible intervention, but 2014 SABRE trial found no change in discharge or adverse events with nebulised HS.
No decrease in hospital admission in 2017 multi-center, RCT for moderate-severe<unk>  with mild adverse events such as worsening of cough were significantly higher in the HS group
Only consider administering to infants who require hospitalization (Class B))

Randomized controlled trials of bronchodilator or corticosteroid therapy have shown mixed results.  Bronchodilators could aggravate the symptoms.
Albuterol/bronchodilator (Class B)
May trial if strong family hx of asthma/atopy in older infants
Racemic Epinephrine (Class B)
Steroids
Consider dexamethasone 0.6-1mg/kg PO or IM x1 in severe cases
