I wasn't talking about adderall or abilify specifically - many medications should not be crushed or split; as a good practice it is good to teach any child taking medications on a regular basis how to swallow pills. I don't recall how old your child is? My kids have been taking medications since 4 or 5 yo if yours is younger liquid form is probably easier for you. If your child needs to continue medications at some point they may prescribe an extended release type medication and those many of you NEVER cut or crush (example concerta)
Most stimulants don't stay in the body for a long time and they also don't usually take 3 weeks to start working (which is case with many mood stabilizers or antidepressants). As far as stimulants causing aggression I can only speak for my kids again the oldest it got rid of much of his aggression but the girls it caused more problems then it helped. Angel was diagnosis bipolar, ODD & adHd at 6yo it wasn't until she was 12yo did she get the Asperger's diagnosis and they drop the ODD & adHd. in my opinion thats why it is so hard to get one solid diagnosis on a kid, diagnosis's are based on behavior and kids are constantly growing and changing.
I didn't mean to come off as sounding critical of what anyone else is doing, was trying to share some of my experience in hopes it might help someone else. As always if you can use any of my post your welcome to it if not please disregard.
