3.5 Head Support (on certain models)

Some infants may need extra support
to keep their head and body in a
comfortable position. Unsnap the sides
and resnap them with the harness
straps threaded through the slots in
the cushion .
If your model does not include a head support, you
may want to use a rolled towel or a blanket for
support .

MAKE SURE THAT NOTHING INTERFERES WITH THE HARNESS OR THE BLANKET. It must still be flat and snug against your child’s shoulders.
