Brief Answer:
Possibly another independent viral infection

Detailed Answer:
Thanks for using the Ask a Doctor service.

I have gone carefully through the details and understand your concern. Most often such symptoms are due to viral infections and antibiotics are ineffective in such cases. Your child possibly has an infection that is independent of the earlier one. Irrespective of treatment it usually spontaneously resolves in 5-7 days. Some children are more prone to catching cold and recurrent episodes are seen. Often such viral infections manifest with fever. If your child is otherwise active and playful, I would not be concerned. If not, it would be a good idea to visit a doctor and to get the child evaluated.

Such infections are frequently associated with an allergic component and it is advisable to give some antiallergic like cetirizine once daily for next few days.

You need to give steam inhalation to your child. It helps in reducing the congestion. Just sit with your child on your lap and place the source of steam before you. The water vapor will be in the air and automatically the child will breathe it in. Water vapor will reach deep inside and would help in diluting the cough and thus would provide relief.

If your child has fever with temperature more than 100°F, you need to give paracetamol or acetaminophen (P-250, Crocin or Tylenol) to it bring down. Also use tepid sponging. If paracetamol is not effective in bringing down the temperature, you need to use Meftal-P (mefenamic acid) which is more effective.

Please be patient. It may take a few days for the recovery to occur. It should spontaneously resolve in 5-7 days.

Hopefully that would help. Feel free to write back in case of further queries.
