The first two to three years of life are critical for early child development (ECD), which affects later life trajectories in health, development, and earning potential. Global calls for early stimulation activities to support optimal development among young children are increasing and there is a need to better understand the factors associated with maternal engagement in early stimulation activities, particularly maternal mental health.

This study examined important factors associated with early stimulation activities performed by mothers of children ages 0–2 in rural Kenya.

Baseline cohort data from an evaluation of an integrated maternal mental health and an ECD intervention included 374 interviews with mothers of children under 24 months. Descriptive and multivariable analyses were performed.

Maternal mental health was not associated with maternal early stimulation activities. Having worked in the past week was associated with more frequent early stimulation activities. At the child level, female sex was associated with more frequent early stimulation activities but prematurity at birth was associated with less frequent early stimulation activities. At the household level, ownership of children's toys and books was associated with more frequent early stimulation activities.

This study indicates that both mothers and families could benefit from availability of ECD-friendly resources such as homemade toys and children's books (particularly for low-income families), and tailored messaging to support early stimulation activities for both girl and boy children and for those prematurely-born. Local governments and community-based programs can aim to both raise awareness about the importance of early childhood development and educate caregivers on specific age-appropriate early stimulation activities that promote optimal growth. Future research should also explore the reciprocal and temporal relationships between maternal mental health and early stimulation activities to inform and elucidate their potential synergistic impact on ECD.
