Discouragement is the hardest feeling to manage, these days. It never seems to diminish. In this video, he is on a 'respite' from the real waling that he does, sometimes for 30 - 45 minutes. He can cry for entire days, with out a break.
I did not post this video, because I wanted advice. If there is something to try, please know that we have tried it. Nothing works. If you think it's his teeth, or he is having growing pains - please know that he is also medicated, with pain medication AND anti anxiety medication. We have been dealing with this sort of crying since he was about 9 months old.
