Taking baby in direct sunlight

My baby is a month old and ive taken her on several walks (30 minutes or so) outside in the sun in her solly wrap and in her stroller. Now I'm reading that you shouldn't take a baby under 6 months old out in the sun because their skin and eyes are extremely susceptible to sun damage. I'm freaking out a bit because I was outside with her earlier and I think she looked directly up at the sun a few times. 😢

Does anyone else take their baby out in the sun? Do you know if this is very dangerous?
