The goal of this randomized controlled trial is to adapt and test a package of interventions to provide nurturing care for children aged 0-2 years in three countries (Botswana, Kenya, Zimbabwe). Mothers living with and without HIV will be enrolled in pregnancy, and their children will be followed for two years. The main objectives of this study are to: * Determine whether the adapted package of interventions improves neurodevelopment among children with and without in utero HIV exposure * Identify why the intervention does or does not impact children's neurodevelopment. Researchers will compare children who receive the intervention package and those who do not to see if the interventions improve child neurodevelopment and growth. Researchers will also compare children with and without HIV exposure to see if there are improvements in neurodevelopment and growth for children who were exposed to HIV. All participants will attend regular prenatal and postnatal care appointments. Participants who are randomized to receive the package of interventions will attend regularly scheduled visits where they will discuss problem-solving strategies, receive information on healthy foods for children, and learn about how to play with their children. Mothers receiving the intervention package will also have the opportunity to meet with other mothers and babies in small groups where their children can play together.
Prior to enrollment for the clinical trial, the three interventions will be culturally adapted and refined in Botswana and Kenya using a user-centered co-design approach. A 3-day participatory workshop will be held to select appropriate adaptations to the three interventions while maintaining core components. Following these adaptations, \~80 pregnant women/mother-infant pairs will be recruited for a formative pilot to further refine the three interventions. The workshop and pilot activities have already been completed in Zimbabwe under a different protocol. Following the clinical trial, we will determine how the package of interventions works (or if it does not work, why) to improve child development. Hypothesized causal biological and behavioral pathways include maternal health, including mental health; infant health and nutrition; caregiving quality; and maternal-child interactions. Throughout the clinical trial, both quantitative and qualitative data will be collected to identify determinants of implementation, acceptability, feasibility, appropriateness, and cost of incorporating the intervention package and neurodevelopmental evaluations into regular maternal and child health services across the three countries. Costing data will also be collected from time and motion cards and study budget records to determine the incremental costs of incorporating the intervention package and neurodevelopmental evaluations in the three participating countries.

After enrollment, participants randomized to BONDS will be linked to a community health worker (CHW) who will arrange Friendship Bench (FB) sessions. During the sessions, participants identify their current stressors, and work with CHWs to consider solutions and select and implement practical solutions.
Community health workers will deliver the infant and young child feeding (IYCF) curriculum between pregnancy and 2 years. Modules in pregnancy will focus on early breastfeeding initiation, exclusive breastfeeding (EBF), how to breastfeed and challenges with breastfeeding. Following birth, modules will reinforce education and support EBF through 6 months and then transition to the introduction of other foods and food preparation demonstrations with continued breastfeeding.
This parent-focused, play-based intervention addresses responsive caregiving and opportunities for early learning. The intervention will emphasize the importance of early learning experiences and adopting a growth mindset, with common themes including the use of scaffolding and "serve and return" activities.
Total Score on the Malawi Developmental Assessment Tool (MDAT) at 24 months
MDAT measures social, language, fine motor and gross motor development using 138 direct observations of children's ability in each domain (gross motor: 36 items; fine motor: 36 items; language: 36 items; social: 30 items). A continuous standardized z-score will be derived based on the total number of items passed by the child across all four domains. Mean differences in total MDAT z-score at 24 months will be compared between the intervention and control arms.

Composite Scores of the MacArthur Bates Communicative Development Inventories (CDI) Vocabulary Checklist

Caregivers are provided a checklist of the \~100 most commonly spoken words in each language that their child speaks. Mean differences in the number of words spoken will be compared between the intervention and control arms.
