PHB P.214 says,
So when wielding a light shield, it is clear you can hold an item in your shield hand. Also it is clear you can use that hand for climbing. And you cannot attack with that hand. Fine.
But can you retrieve and use a consumable item with a shield hand when wearing a Light Shield?
Assuming you are using a weapon and a Light Shield, do you need to sheath a weapon or stow a shield to retrieve, say, a Potion of Healing from your backpack and drink?
Light Shield: You need to use your shield hand to wield a light shield properly. You can still use that hand to hold another item, to climb, or the like. However, you can’t use your shield hand to make attacks.
