Peekaboo is a classic, timeless hide-and-seek baby game. It has no rules. It can be played anywhere, anytime. It stimulates baby's senses, encourages social development, and language development. It helps reinforce "object permanance", which means that something still exists when it's covered, behind something, or disappeared into another room.
Babies start to better understand the concept of object permanence by month 8. By months 9 to 12, baby will likely be able to play peekaboo on her/his own.
Playing peekaboo is simple. You cover your face and uncover it while saying, "Peekaboo!" or "Peekaboo I see you!" Alternatively, you can also use a blanket by covering and uncovering your face.
You can play further with the use of language in ASL, such as "The Animal Peekaboo" as shown in the video. It uses handshape-based nursery rhymes. A combo of nursery rhymes and peekaboo. What a bonus!
The video shows a fun, interactive reading and play, using a book (title?). Each page has a face of an animal with the folded extended page to cover and uncover. At the end of the book, there is a mirror with the extended page that would cover and uncover the baby's face!
This documentation project follows a baby's language acquisition, literacy development, and phonological acquisition in sign language, specifically ASL, week by week from gazing at birth to manual babbling, to first words just before the first birthday in a natural native-ASL environment and visual culture.
The second-year documentation continues to follow the same one-year-old child's language and phonological acquisition and literacy development in ASL on a weekly basis from the one-word stage to two-word and multiple utterances.
The third year documentation continues to follow the same child's ASL language and literacy development on a regular basis from age two to three. It surveys ASL phonological acquisition and more complex utterances.
The fourth year documentation continues to follow the same child's ASL language and literacy development on a regular basis from age three to four. It surveys ASL phonological acquisition and more complex utterances.
This five-year documentation and project follows the bilingual child's natural language acquisition in sign language from newborn to age five.
