While still holding the child securely, close the
open leg hole by reattaching the "hook & loop"
and fastening the buckle. Adjust both leg hole
openings to snugly fit the baby's legs.
9.
While still supporting the baby's weight, fasten
the "head support buckle" by inserting the
upper portion of the buckle (on the shoulder
strap) into the lower section (located on the
head support). Push the "side closure buckle"
together until you hear a click. Before releasing
your hold of the baby, ensure that the "side
closure buckle" is locked in place by pulling
down on the buckle.

If necessary, tighten the "shoulder straps" by
pulling forward on the webbing portion at the
base of the strap while gently lifting the baby
by the bottom. When the straps are properly
tightened, you should be able to kiss the top
of your child's head.
