“…Since a 6-18-month-old baby should have opportunities to be stimulated by its parent and the environment, the design of a carrier should allow a baby those opportunities, i.e., the carrier should have a padded frame that can support the baby for a long time without tiring it, and the carrier should let the baby face out toward the environment and away from the torso of the parent. Bleah & Ellett, 2010;Fista et al, 2019;Brown et al, 2018;Lee & Hong, 2018 The structure of a baby carrier today has not been designed with the ergonomic of elderly people in mind because the shape of the carrier does not fit their body well (Bleah & Ellett, 2010). In addition, there is a relatively wide gap between the carrier and the person carrying the baby, hence it is possible that the baby may wriggle out of the cradle of the carrier and fall.…”
