Aussie Games :-)
Aussies will sometimes make up "games". My 6-month old has made one that is kind of cute but also a bit annoying. She likes to get a toy or rope or ball or anything and carry it behind me while I'm walking and constantly poke my leg with the toy. Not just for a few steps but for long distances in the house. I haven't figured out how to communicate to her what it is that she is doing that is not exactly a lot of fun for me. I play with her a lot, so she is not starved for attention, she just enjoys doing this occasionally.
(She also likes sometimes to chew her toys on my leg when I am sitting down. This is a bit scary since she has on two occasions pinched a little skin when doing this. This one I can control – but how to deal with the poking of the back of my legs while walking I do not know.)
