Hello there!
Erin seems to be a pretty normal kid. Just because she dislikes work, and extracuricular, does not make her very different from anyone else. Some children may just need a little extra help to do things. She may be autistic, and have problems with her work. Erikson, though, should not make any assumtions until she has full on proof Erin has problems.
Hope this helps you!
