Mathieu Chedid - les doudous enchantés (by Doudousolidaires)
extraordinairedem: This video might interest you; it shows some of the other shots from the same photo session where Matthieu posed with the little stuffed dog.
Also, I wanted to point out some important French child-slang words that might come in handy:
“doudou”: literally “soft-soft”; a plush animal, doll, or blanket a child sleeps with.
“do-do”: the closest equivalent I can find is “beddy-bye”. So “fait do-do” would translate roughly speaking as “go beddy-bye” or “go sleepy-bye”.
