Tell your ex that medicine isn’t always the answer. Medicine should always be the last resort, because of the side effects. There are different ways to deal with stimming and jumping. It is a form of excitement or nervousness. Help him to release some of his energy through activity. Tell your ex to read up on it, give him some info from social stories on a site called, teacherspayteachers.com.

If his case is not severe there really are other alternative routes to go down. Many bio meds, bath salts, oils, and diet you can use to get him to tone down. I used to use focalin for ADHD for my daughter. Now it's all diet & bio meds and activities to substitute OT plus socializing.

Don't ignore the meds as a possibility. We swear by guanfacine for ADHD issues. If it doesn't work then discontinue using it but to not try it due to fears or whatever doesn't make sense to me. I was anti-med for ASD kids until my daughter proved otherwise.

There arent all that many meds that require a doctors perscription that are available for a four year opd- unless there are lots that we were not offered! I would suggest that you explain to your ex that until your son is older, there arent many options. As he gets older more choices will appear; and by that time you may have more idea of what kind of help- if any- that he might need.

Medication is not always the solution my son will soon be 5 and is under ASD, due to him always being on the edge and very active i try to keep him involved in activities or even take him to park on days when nothing else is available.
Hope it helps.
