I am raising my child bilingual and I usually talk to him in my native tongue, however I sing to him English nursery rhymes as we don't have them and I have grown to like them myself .
I used to sing to him in Italian up until he was around 10 months and then it has all been in English.
DS is now 18 months old and can sing at least 4 English nursery rhymes, everybody can understand his tune and if you know the songs you can also make up what he is singing but he's not very clear yet.
HOWEVER tonight he started singing this Italian song very clearly - he said 4 Italian words together! and also clapped his hands (this song says "clap your hands").
He cannot possibly have any exposure to this song anywhere where we live, and last time he heard it as I said was at least 8 months ago.
This shocked me, can he remember and reproduce something which he heard so long ago when he seemed not even interested in the song?
Any similar experience would be highly appreciated
