"I didn't need you to protect me. You could've gotten hurt!" Your mother sometimes forgets that you are basically a God like your father. Or maybe Lois remembers that fact and just can't turn off her motherly overprotective behaviour. How possibly can she? She held you when you were just born in her arms, Lois remembers your fingers being so small and delicate, so helpless and fragile. She can't just remove those memories, feelings, and worries because now you are a superhero too.
