We're gearing up to open up Lookit to more research labs! Our first study for newborns, "Baby See, Baby Do?" is live, and "Baby Euclid" is back for 7-month-olds. And we're still recruiting for Flurps and Zazzes, Your Baby the Physicist, and Baby Laughter - please help us spread the word!

Data collection is complete for the Lookit studies "Baby Euclid," "Mind and Manners", "Flurps and Zazzes," and "Words and Objects" (but stay tuned for follow-ups!). We're still looking families with babies to participate in "Look and Listen," "Your Baby the Physicist," and "Baby Laughter Games."
