“…Behaviors such as putting the hands in their mouth, gaze aversion, closing their eyes, being distracted by objects, touching parts of their body, are self-regulating responses that can be part of the infant's repertoire that should be observed during the procedure. In addition, although FFSF is a worldwide used procedure to assess infant emotion self-regulation skills, studies with Brazilian samples are scarce (Chiodelli, 2016;Ribeiro, 2017). Therefore, in view of the intent to expand studies on mother-infant interaction in the framework of the FFSF paradigm, the present study seeks to: (a) describe and compare the behaviors of mothers of very premature infants in the FFSF play and reunion episodes, (b) describe and compare the behaviors of very preterm infants in the three episodes of FFSF and, (c) describe the correlation between maternal behavior and very preterm infants.…”
