My 2 month old has got wet cough past 2 days and has no fever. She is taking feeds and is able to sleep. However, her wake window has become bit less. Everytime she wakes up, takes feed and after sometime, goes back to sleep. But when she is awake, i can feel some cough while breathing. I am giving her nasoclear drops in her nose every 1.5 or 2 hours. Is this all normal ? And how long does it take for an infant to recover from cold and cough ?
