Do you want actual .ldr files of models to download?
Or do you just want instructions for simple models your kid can build?
If the latter, the Peeron site has instructions for simpler sets from the 70s/80s which might suit.
Here's an example:
http://peeron.com/inv/sets/533-1
On that page you get to see the parts list, and there's a "Available from PICSL" link for scans of the instructions pages that takes you here:
http://peeron.com/cgi-bin/invcgis/scans/533-1/?ct=1
You can find similar sets by searching or browsing themes related to "basic" and "universal" amongst others:
http://peeron.com/inv/theme/LEGO/BASIC
http://peeron.com/inv/theme/LEGO/Universal
http://peeron.com/inv/theme/LEGO/BASIC/U...ilding_Set
http://peeron.com/cgi-bin/invcgis/psearc...mit=themes
http://peeron.com/scans/?tid=30&s=0
http://peeron.com/scans/?tid=29&s=0
Not all sets have instructions available though.
The ones that do are indexed here:
