Amanda Peet dished about her 18 month old daughter, Frances Pen’s first words.

“I think Dada was her first word. She says ‘Hi Dada, Hi Mama,’ and she does sign language so she’ll say ‘I love you’ (in sign language)” said the actress. ” When the lights turn green in the car, she’ll say ‘Go, go, go!’”

The most popular baby’s first words are generally common and proper nouns, such as: “Mama,” “Dada,” “doggie,” “shoe,” “diaper,” “spoon,” “cup,” or “apple”.
