Hi,
It is exciting!
After Jannaeus started with mumbling ba- ba- ba, and went over to mumble ma-ma-ma he got to the real thing: he called me Aba! 
(dad in Hebrew).I went excited and started to tell anybody about it.
Until I talked with my Ima – who told me the story how my father went like a peacock and show off how my elder sister started to call him Aba. And then he realized that Jannaeus use this word for everything: the trees, the cats, the cars, Ima….
And soon enough I realized that Jannaeus also calls everything Aba….Everything except Ima =)
Jannaeus also started walking! well not walking for miles, but three steps is enough for now =)
Take Care
