My 1 year old has a bad cough?

Hello, thank you for your question!

A treatment with antibiotics can take up to 72 hours before it starts to be effective

For your second question, amoxicillin can be used to treat pneumonia but the dose to treat it could be different versus an otitis. It is impossible for me to question the diagnosis that has been made. If you do not see any improvement in your child's condition, you will need to be re-consulted

I hope this helps and I am available if you have any further questions!
