Hi there!  My daughter is special needs but not diagnosed Autistic.  However, she is non-verbal at this point (4.5 years old).  She loves the iPad.  Can anyone recommend a great program or app to help her better communicate her wants/needs?  She knows her alphabet and understands a ton.  She just can't get it out.  I've searched for apps and they range from free to $100.  I'm just not sure what the right route is to go for her at 4.5 years old.  Any comments/suggestions?
