Hi, I’m sorry that you and you’re grandson are having a bit of a tough time. I’m not a doctor, but it could be the “crash” from the Adderall making him emotional or simply the drug itself, on top of the fact that he is a 7 year old. I’m assuming he was diagnosed with ADHD and thus put on the stimulants but I would urge you to be very cautious here. I personally think 7 years old is way too young to be on this drug. Your brain does not finish developing until your around 25, thus his brain is still very much in the developmental stage. I would honestly wait until he is older to put him on a medication but that’s just my 2 cents. Good luck and take care
