Language acquisition in sign language

Studies (Petitto) show that the stages of language acquisition from birth to age 5 and beyond are identical among infants in both sign language and speech.

Furthermore, study (Petitto and Marentette) found that bilingual-bimodal hearing infants exposed to signed and spoken languages do babbling in both manual and vocal within the same developmental stages of language.
