If baby falls asleep on your back in Double Hammock and his heads is lolling sideways, you can use the strap on the same side to cover his head.
Grap the upper rail of the strap that is closest to baby's head
Pull it upwards to get some slack
Bring the slack to baby's head (cover his hair, not his face).
This is easier if you bend a little and baby's head can come closer to your back.
Important: when Baby's asleep, his limbs will relax, so you may need to adjust or tighten the wrap a bit. Make sure his knees are high enough so that his head his properly supported.
