The present degree work was carried out within the framework of the systematization modality of practice, specifically the one called Families, Links and Violence, part of the psychology program of the Pontificia Universidad Javeriana. The main objective of this systematization was to characterize the experience of mothers who are part of the Integral Kangaroo Mother Program (IKMP) when having premature or underweight babies, taking into account the experience of pregnancy and childbirth, the perception of the IKMP, the networks of support and the life project. This qualitative research was conducted, through which semi-structured interviews to 20 young mothers within an age range of 20 to 25 years. The information collected was analyzed and interpreted with the fundamental theory method in the data through open coding. The results indicate that this group of mothers presents risk factors for mother and child bonding with premature or underweight babies, because of their life history, a weak support network and their life centered project in themselves, this is due to the moment of the life cycle in which they are. All of which ends up impacting adherence to the IKMO. Likewise, it is necessary to add that to a certain extent the support network represents a protective factor for this as well, due to the help provided by the couple and some relatives of the mothers, which indicates that this factor is ambivalent.
