Re: OCD and kids
I forgot that the early interventions at home generally end @36 months.
The behaviors certainly seem consistent with OCD traits, which would not be too surprising since your DH has tendencies (heritability factor).
I am so glad you have someone you can really trust! You're being proactive and advocating for your child and the importance really cannot be overstated.
Even with the symptomology you have mentioned I think his prognosis is EXCELLENT with your love and support and proper intervention.
Please keep us up to date on how Adam is doing.
