The apparent 'Mama's and 'Papa's I've taken with a big pinch of salt, 'tis all a part of normal babbling. I remember DD shocking us by appearing to say 'Mama' and 'Papa' at some point (although I think it was later) and then not actually saying it until she was older.
But, yesterday he appeared to say the Dutch word for food really quite clearly when he was desperately grabbing at his dinner while DP struggled to put his bib on. The word is 'eten' (prn 8-un) which isn't really isn't at all like any of the typical Dutch or English babbled syllables. He's seemed to say 'Haar' (hair) a couple of times too
Please tell me if there is actually some vague possibility that he could be producing words, or if this is all some sort of weird projection. I really don't spend any much time paying attention to his development at all like I did with PFB DD.
