Whats the best way to help a 5 month old with chest congestion?
What you're about to hear sounds very odd. But worked everytime for my son....
Old remedy: Take vapo rub and coat the bottom of the childs feet with a think layer before you lay them down for bed at night. Cover the think layer of vapo-rub with socks and send them to sleep.
I did this with my son 3 -4 times as an infant and he woke up MUCH better.
