These video recordings (with limited transcriptions for just a few files) were made by Dr. Nini Hoiting, developmental linguist at the Royal Kentalis institute for the deaf "H.D. Guyot" in Haren, Groningen, the Netherlands, between 1988 and 2009. Most recordings were not used for academic research on language development, but for monitoring the children's language development.
