Jonas The Lion

I've been wondering when Jonas would start making animal noises and it occurred to me that I haven't really been teaching him any.  So today we were playing with a lion and I kept saying, "What does the lion say?" and then I would make a couple roars.  After a little while I asked him, "Jonas, what does the lion say?" and he actually roared back and kept on doing it after I asked him.  He gets it!!!  So cute.
