Bosnian-Croatian-Serbian [NB Alphabetical Order] child acquisition?

[Jules Levin]

I have a grad student in psycholinguistics in my [general] morphology class
who wants to do a paper on child acquisition of B-C-S-ian.  For some reason
she wants to look at that language[s] although she doesn't read it.
Is there a data base for child acquisition that we have any hope of
obtaining in the next coupla weeks?    I told her if the data were good
enuf I would translate the corpus for her.  Is there anything published in
English?

Is anyone familiar--just in case-- with such a data base for any
morphologically rich language (apart from the great one for Russian by
Gvozdev?
