Babble Boot Camp© for Preterm Infants: A Trial of a Proactive Speech/Language Intervention

Babble Boot Camp (BBC) is an evidence-based proactive, systematic, and longitudinal speech/language intervention for babies ages 2-24 months of age to infants and toddlers at risk of communication impairment (Peter et al., 2020). The approach was designed to prevent or minimize speech and language disorders in infants at predictable risk by fostering precursor and early communication skills via parent training (Potter et.al, 2023). BBC is parent or caregiver implemented to reinforce functional, practical, and developmentally appropriate prelinguistic and early speech skills (Peter et al., 2020). Specifically targeted treatment routines include a "word bath" with infant directed prosody, facial expressions, responding to infant vocalizations, modeling and reinforcing babbling, labeling objects, modeling word productions, and recasting/expanding upon the child's utterances (Peter et. Al., 2021; Peter et.al.,2025). BBC has been trialed with great success in Classic Galactosemia, and with feasibility for children with Down Syndrome (Peter et al., 2021; Peter et al., 2025). During the weekly 15-20-minute speech therapy sessions, the speech pathologist follows a Teach-Model-Coach-Review-Questions format based on the teach-model-coach-review instructional approach (Robert et.al., 2014). Parents are then to implement learned strategies and routines daily including the addition of watching videos of babies babbling and joint picture book reading. All routines are targeted on what the child can access with support to account for the Zone of Proximal Development (Vygotsky, 1979). BBC researchers were able to show the intervention was feasible for families in the original trial group containing children with Classic Galacosemia (Finestack et. al, 2022). This suggests that BBC could potentially be possible to use with other populations.

In this trial, the intervention program commences at 6 months corrected age and continues via telehealth up to 12 months' corrected age. The intervention is delivered by a speech pathologist. This randomised controlled trial (RCT) of BBC compared with usual care, will evaluate the efficacy of BBC intervention which is delivered earlier than traditional health service models provide, at a more developmentally appropriate time, and unrestricted by geographical location, for infants born preterm and their families.

The primary goal of this trial is to examine the efficacy of BBC with children born preterm. Additional secondary outcomes include parent compliance, parent views of the trial, and describing the participants with highest attendance. A further exploratory outcome to be measured will include family impact of treatment on depression/anxiety/stress.
