Hi Raki! I think ABA would be helpful for both speech and behavior if that route is better for your budget, but I think having all three specialties might be more effective. Ask your provider if ABA can be completed with an RBT instead of a BCBA, which tends to be a more affordable option. That way, per budget, you could potentially add speech and OT. Hope this helps!

I definitely think the combination is the best way to go for a 2 yr. old. My son is also nonverbal & ABA was too intense & inflexible for him. I would recommend starting with no more than 2 hours of ABA itself per session/day for his age so as to not overwhelm him. If overwhelmed ABA can be detrimental.
ST is normally a 50 minute session & OT is also. I would go for 3 days per week of ST, more if you can get it. You would base your child’s OT hours based on his fine & gross motor skills level. My best advice is to make sure your child’s therapists are making therapy fun because this is key for his success. My son is 7 yrs. old now & his progress has always depended on the therapist having the right mind set & personality.
