Acquisition of possessive -s

[MariaMcGuckian at aol.com]

Dear info-childes members,

I am a PhD student at the University of Ulster under the supervision of Prof.
Alison Henry. I am currently conducting research concerned with the
acquisition of grammatical morphemes by English-speaking children with
language disorders.

I would be very grateful if anyone on the list could provide me with
references to literature on the acquisition of English possessive -s.
Unfortunately my database searches have yielded few references.

I will post a summary of replies.

Thank you for your help.
