New Tools or Underwear?

Hell I can't even buy clothes at "normal" stores for my boy. Just turned 16 last week HE'S 6'8" and 300 LBS!!! Wears size 18 shoes!!! Even t-shirts cost $30 if you want them long enough to cover his butt crack!!! We get asked all the "What the hell are you feeding that kid?" Our reply is MIRACLE GROW!! LOL
The way my three eat you would think they was that big. My youngest is the runt and he can out eat the 2 older ones. And they eat alot lol
