Sleep is "beep." She puts her babies in her bed, turns off the lights and announces to us all that her babies are "beeping."
Finger is "ninger." At least once a day, one of her "ningers" needs a band-aid (so she says).
My is "I." Stuck is "tuck." "My tuck! My tuck!" (This cry is usually preceeded by her climbing into the baby's exersaucer.)
