Kids and behavior meds

So, I find it completely frustrating that my SO's ex has decided to give their son behavior medication at the age of 6. I would understand if she was the type of mom who disciplines him, but shed rather put him on 9 pills a day and place him in front of a computer all day. He has no sleep schedule. He has since threatened to kill himself and had to go to a children's psych ward for 72 hours.

And ended up with more pills!

How is his Dr OK with this??
