So far, the little monster has used two sentences.
The first, a few nights ago, was "Mum, no!" (Mum being in English and No in his other language) when I tried to put him back in his crib after a night feed.
The second, today, I told him we needed to change his diaper and he responded with "[his name] dai dai?"
Yeah, not going to lie, I'm a little freaked out. Mostly delighted, but eep. He's only 11 months.
