3rd personal singular morpheme - bilinguals

[Cynthia Core]

Hello -
I recently saw an article (Acquisition of the English plural morpheme by native Mandarin-speaking children), and it sparked my curiousity.  I did a brief search, but did not find any articles that look at morpheme acquisition by bilingual children.  Does anyone know of researchers working in this area?  Specifically, I am interested in English 3rd pers sing morpheme by native
Spanish-speaking children.
Thank you.
