Two year old obsessed with basil

This might sound silly but here goes. I have an almost two year old who loooooooooves basil. We have a basil plant and anytime she sees it she wants to eat some, “basil, basil, basil!” I give her 3-4 leaves at a time but she always wants more. Is it safe to give her more? I’ve never done so thinking it might be too acidic or something. Any insight?
