Tounge tied baby... Im stressed

Being "tounge tied" is when the piece under the tounge is tight. With this babyhas had issues latching onto my breast and can't do it at all without a nipple shield. Feedings have been so hard and after he eats i also have to give him formula to make up for what hes not getting. I feel super stressed about it and im really scared that hes still not giving him enough and hes being starved or something, which i know he's not and tge pediatrition has told me to continue the way in doing.

I was just wonderung if anyone else has delt with this or know any tips or tricks for tounge tied babies. Id really appreciate any help.
