This chapter describes the caregiving practices and interaction patterns that children in Menamaty experience during the first three years of life, based primarily on video-documented spot observations and event observations. It moves from detailed descriptions of various forms of carrying and body contact to primary care practices such as bathing, breastfeeding, and spoon-feeding, and then to object play and face-to-face interactions. It documents how these practices change over the first three years and differentiates them according to children’s social partners. The findings reveal a clear division of roles: caregivers, with mothers at the centre, focus on children’s physical well-being and soothing, while other children, especially those of a similar age, engage in cognitively and emotionally stimulating interactions. The chapter argues that the dynamic ontogenetic changes in young children’s social worlds are closely tied to this division of roles. As children gradually acquire motor independence, their reliance on body-centred care provided by mothers and other caregivers decreases rapidly. At the same time, these developments enable them to spend more time exploring their environment with peers, who are abundantly available as play partners. The chapter concludes that children’s early learning and socio-emotional development can only be adequately understood if analysis moves beyond parents and caregivers more generally.
