This study aimed to identify how child care is delivered to children under two in their daily routine. Based on a qualitative approach, the study addresses the care site in the child care, through non-structured interviews with mothers and professionals from two health units in peripheral areas of Ribeirão Preto, SP, Brazil. Results point aspects of how professionals view the mothers and their families, how the child's health, the routine and eventuality of care are followed. Adherence is important in the child's follow up, the longitudinality of care and, mainly, the concern with the mothers' and families' values. Child care in primary health care has a contingency character; it must deal with eventuality, uncertainty and events linked to experiences, integrating practical and technical knowledge.
