Purpose: Dyadic caregiver–child interactions are commonly used to examine children’s language learning environments. However, children frequently interact with multiple caregivers and/or siblings if they come from homes with multiple caregivers and siblings. Thus, we examined if and how caregiver opportunities to respond (OTRs) varied when sampled across three interaction configurations.

Method: Twelve children with Down syndrome (Mage = 40.82 months) and their biological parents participated in the current study. We collected separate mother–child and father–child dyadic interactions and one family choice interaction (i.e., both caregivers present and occasionally siblings) in families’ homes. We analyzed if differences in the caregiver’s OTR frequency and type—explicit and implicit—existed among dyadic and family choice configurations.

Results: We found that, during family choice interactions, children were exposed to fewer OTRs when combining the total number of father and mother OTRs compared to dyadic caregiver–child interactions. This effect was large for explicit OTRs (mother-dyadic vs. combined family choice: g = −1.99, confidence interval [CI] [−3.00, −1.00]; father-dyadic vs. combined family choice: g = −0.84, CI [−1.84, −0.11]). For implicit OTRs, effects were small for mother-dyadic versus combined family choice (g = −0.34, CI [−1.17, 0.48]) and negligible when comparing father-dyadic with combined family choice (g = −0.08, CI [−0.90, 0.73]).

Conclusion: Our preliminary findings highlight the need for a more nuanced understanding of children’s language learning environments to better understand how caregivers support their children’s language development.
