Age Guidelines
Prior to first use, consult with your
pediatrician regarding suitability of
stroller use with your child.
Infants incapable of holding their
head up must have additional head
and neck support to ride safely and
comfortably. From 0-8 weeks, or as
recommended by your pediatrician,
the use of an infant car seat and
adapter is encouraged.
Children are unique and develop at
different rates. Most may not have the
neck strength for jogging or off-road
motion until 8 months of age. For
jogging or off-road stroller use, BOB
Gear by Britax recommends you limit
use of this stroller to children over the
age of 8 months.
