Sounds crazy, but my 4yr old is making this horrible pig snorting sound (through his mouth not nose) when he eats. It's gotten worse over the last week. It's stared about 3 weeks ago. It doesn't happen in his sleep and not very much when resting. At first I thought it would pass, but it seems to have worsen. I asked him to stop and he said he can't! I tried to "teach" him how to breath through his nose while eating or quietly through his mouth but it doesn't work. I've booked Gp appointment but was wondering if anyone has any idea what this could be. Thanks.
