Much of infant development occurs in the home and in the context of caregiving support. Babies learn through their everyday interactions with parents—from watching, listening, communicating, cuddling, and playing with them. Foundations for cognitive skills such as attention, perception, learning, and language are all built in the brain during the first year of life. Socioemotional development, including the ability to self-regulate behaviors and emotions, also begins during infancy. Recent advances have allowed researchers to answer questions about the developing brain and how it is impacted by experience and environmental systems, including parental sensitivity and consistency, the home environment, socio-cultural factors, community support systems, and public policies. Giving parents the opportunity to support healthy infant development through paid parental leave programs that are accessible, flexible, and equitable, will positively impact early trajectories of brain and behavioral development. 

Abstract Bilingual infants from 6‐ to 24‐months of age are more likely to generalize, flexibly reproducing actions on novel objects significantly more often than age‐matched monolingual infants are. In the current study, we examine whether the addition of novel verbal labels enhances memory generalization in a perceptually complex imitation task. We hypothesized that labels would provide an additional retrieval cue and aid memory generalization for bilingual infants. Specifically, we hypothesized that bilinguals might be more likely than monolinguals to map multiple perceptual features onto a novel label and therefore show enhanced generalization. Eighty‐seven 18‐month‐old monolingual and bilingual infants were randomly assigned to one of two experimental conditions or a baseline control condition. In the experimental conditions, either no label or a novel label was added during demonstration and again at the beginning of the test session. After a 24‐hr delay, infants were tested with the same stimulus set to test cued recall and with a perceptually different but functionally equivalent stimulus set to test memory generalization. Bilinguals performed significantly above baseline on both cued recall and memory generalization in both experimental conditions, whereas monolinguals performed significantly above baseline only on cued recall in both experimental conditions. These findings show a difference between monolinguals and bilinguals in memory generalization and suggest that generalization differences between groups may arise from visual perceptual processing rather than linguistic processing.
