In English, parents usually talk to their kids differently from how they usually talk. The words they use when doing so usually ends in -y. For example, "kitten" becomes "kitty", "I" usually turns into "Mommy" or "Daddy" depending on who the parent is, and "wakie wakie!" is used when waking the kids up.
Are there any patterns in Japanese child-directed speech? How are the words changed when parents talk to their kids?
Note: I read from other posts that s- sounds are changed to sh-, ch- or sometimes p- sounds in a little child's speech. But do parents speak to their kids this way as well?
