Child: care, health and development
-
To explore how infants with developmental delays express pain, we analysed facial expressions of infants receiving their routine immunization at around 4-6 months developmental age. The sample included eight infants with developmental disabilities (mean developmental age 4.8 months) and 30 typically developing infants (mean age 4 months). The Maximally Discriminative Facial Movement Coding system was used to code infant facial expressions during immunization. ⋯ Infants with developmental delays were likely to show pain in facial expressions less clearly than typically developing infants. It is important for health care professionals to be aware that this may be the case when considering the administration of analgesia for such children.
