People seem to have a lot of spare time on their hands picking on a little kid

Nice one!...
As I stated earlier he was not ignorant when I met him & his father & seemed to me
to be inquisitive & asked a lot of questions etc...
To me that show to some degree that they are not ignorant
& are looking to seek knowledge to better care for & look after their animals.
At the end of the day though gecko's
if you bearded had perked back up & is now going down hill again..
A vet trip may be warranted just to be on the safe side, undigested scat is not a good sign
& seeing as you have already tried to change several husbandry issues perhaps
it is something that needs to be looked into in depth by a professional.
I still stand by my first statement..
Good luck with your girl & I hope you get the issue sorted asap.
Cheers
