It is understood that the baby, being physically and psychically immature in the first years of his life, needs an adult who dedicates to him, in addition to the basic care to the maintenance of bodily health, the emotional investment capable of helping him to develop subjective skills necessary for the maintenance of relationships with himself and with the world. In this sense, understanding that the family and/or caregivers play a fundamental role in supporting development, through the subjective path of affection, the research presented, based on theoretical concepts of child development, socio-emotional learning and self-care, as well as on the content of interviews with three participating families, aimed to build guidance and support material, in order to contribute to the process of promoting socio-emotional skills in children in very early childhood. The reports presented in the interviews demonstrated the significant importance that families have attributed to subjective development, understanding and valuing the need for contact and the affective care relationship with their babies. In this sense, it was also verified the investment that mothers make in the transmission, by encouraging learning, socio-emotional development, advocating scientific aspects and the construction of their own experiences with their babies to the detriment of transmissions of popular knowledge (myths). As for self-care, it was noticed that, in general, the difficulty of families, especially mothers, in naturalizing self-care as part of their routines is still significant, which includes their babies who demand constant care.
