My 2.5 yrs old still drools and rather excessively. Has to change his t-shirt almost every 2-3 hrs He has started speaking in full sentences and singing nudsery rhymes. Eats and drinks reasonably well. Our PD and a TCM practitioner said he's fine and that some kids are like that but i still worry. Perhaps I'm being paranoid but wonder if anyone has had or encountered similar experience. TIA!
