My little girl just turned three, and she talks a lot – in French, but liberally sprinkled with German words, such as:
“Donne-moi da [das] Buch.”
If you ask her “How does mommy say?”, she’ll immediately provide German words for such terms as aujourd’hui – heute (today), jaune – gelb (yellow) or hippo – Nilpferd (hippo).
This is a fun stage. 🙂
