My little boy is exactly 21 months old today. He's developmentally sound. Great language skills, great fine/gross motor skills and really cheery.

The issue is that he's been drooling at a constant clip since he was 3 months old. When he's teething or sick, we expect it. My boy drool's constantly, though. When he's perfectly healthy, he's drooling. My wife compares him to a snail that leaves a trail wherever he goes.

We talked to our ped about this at a recent visit, and he recommended we see a speech therapist. We took booger man to one for a checkup.

She confirmed what we believed when it comes to his development: he's ahead of where he should be in almost every facet. In fact, she said that based on the amount of drooling he does, she was stunned that he's moving along as well as he is.

Her explanation for the drooling is that my son as slightly low facial muscle tone. We've been given exercises and daily massaging instructions in order to tighten these muscles up.

We've just started the process.
<bot>: 21 month old drools constantly. Doctor recommended facial massage and exercises to resolve issue. Anyone have any experience with this?
