Toddler Vomiting Phlegm Frequently
by Kizzy
(London, United Kingdom)
My son who is 20 months old has just started holding the back of his neck. He has been vomiting phlegm for the last 4 hours like maybe every hour.
I have also noticed that he wont close his mouth and saliva keeps running from his mouth.
What could be the cause of this?
There are no other noticeable symptoms.
