The narrow setting can be used for newborns and babies at a minimum weight of 7 lbs until approximately 0 - 3 months.
The middle setting can be used for babies 3 - 9 months of age, and the widest setting is suitable for taller babies, approximately 9 months and older.
Please note that these recommendations are guidelines and may vary depending on the height and size of the individual baby.*
*Correct positioning: The width of the panel should be determined by the individual baby's comfort and leg span. When choosing which seat width to use with your baby, choose the width that supports their legs in an "M" shaped, spread-squat position with their legs supported to the crease of the knees.
If the edge of the panel rests on the baby's calves, rather than under the bend in their knees, then the width you have chosen is too wide. Always ensure proper placement of baby in the carrier including leg placement.
