Sunscreen for babies under 6 months?


I’m just curious when everyone thinks about this. My daughter had her 2 month check up today. Her doctor told me sunscreen says 6 months and older, but it’s actually okay for babies 2 months and older. She said to try to keep her in the shade as much as possible and use protective clothing as well. Has anyone used sunscreen on their babies under 6 months? I was always under the impression you HAD to wait until then. Picture of my sweet 2 month old, who will likely be spending lots of time outside with her big sister!
