Welcome to Healthcare magic forum.
Your baby is most probably suffering from a respiratory infection causing chest congestion, wheezing and secondarily vomiting.
Wikoryl suspension can reduce cold symptoms like rhinitis and dry cough but if there is any bronchospasm
and associated chest congestion that will not be releived.Also phenylephrine
contained in wikoryl suspension is contraindicated for infants due to it's sideeffects.
Colimex df drops can relieve abdominal colic in infants
but not vomiting .
So please do not selfmedicate such a young infant and as far as possible consult a pediatrician
for evaluation of your child and appropriate management .sometimes antibiotics might be needed to prevent complications like pneumonia
so do consult your doctor for the best relief.
Wish your child a speedy recovery.
