Nearly 3 y old still drooling constantly, what's up with that?

[Jay69]

Anyone seen/heard of this before? Ds2 constantly needs to be told to swallow. Wonder if it could be nose blockage causing him to breathe through his mouth or that his palate hasn't developed yet?

could be too many salivary glands/over-production of saliva - a friend of mine's DS had this

my cousin's child had this. The doctor recommended the child had his tonsils out, and the problem stopped.
