It sounds like a pretty low fever, which my kids have had before without other symptoms too. I wouldn't give her Tylenol at this point unless she's acting not as playful and you can tell it's affecting her. It's better to buy the regular Motrin & Tylenol without the cold or flu added ingredients. That way if later down the road you do need to keep a fever down you can alternate the Motrin & Tylenol without overdosing on the cold/flu medications in them. Buy a product that does the cold/flu symptoms separate.
