in my opinion it is not too young to have a multidisciplinary evaluation. I don't know that schools do these?
I would guess that the behavorial observation would be used to develop a Behavioral Intervention Plan (BIP). I don't know if that's enough to qualify for an IEP but to me if they are sending him home so much he needs one.
I'm sure others will be along soon who will know more. Hugs.
