I’m not sure what Ben’s very first word was (though ‘mama’ is in with a good shout), but here are his first words. He’s built up a good little vocabulary.
‘Mama’
‘Dada’ (only recently)
‘Tada’ (Czech for ‘here’)
‘Jeste’ (Czech for ‘more’)
‘Hiya!’
‘Baba’ (bye-bye)
‘Ne!’ (Czech for ‘no’)
‘Go!’
‘There’ (when he brings something to show you).
