Parents’ contingent responses in communication with 10-month-old children in a clinical group with typical or late babbling

ABSTRACTParental responsive behaviour in communication has a positive effect on child speech and language development. Absence of canonical babbling (CB) in 10–month–old infants is considered a risk factor for developmental difficulties, yet little is known about parental responsiveness in this group of children. The purpose of the current study was to examine proportion and type of parental responsive utterances after CB and vocalization utterances respectively in a clinical group of children with otitis media with effusion, with or without cleft palate.
