The appropriate time to remove the padding or cushioning designed for smaller babies in a car seat is determined by several factors, primarily the child’s weight, height, and how well the harness fits without it. These inserts are specifically included to provide a snug and secure fit for newborns and smaller infants. An example would be needing to remove the insert to achieve a proper harness adjustment where the straps are at or below the infants shoulders in a rear-facing configuration.
Utilizing infant car seat inserts as long as necessary ensures optimal safety by providing a better fit and preventing the child from slumping or shifting within the seat. This can significantly reduce the risk of injury in the event of a collision. Historically, these inserts were developed to address the safety concerns associated with placing smaller infants in car seats designed for a broader weight and height range.
