Beach visit with young one

Tiffany • Abby came early emergency c-section. 3/3/17💕 Mommy & daddy are so in love! RIP to my fiancé. 5/21/17 gone way too soon
We are going to the beach in 2 weeks and my daughter will be 2 months. I know having a baby out in the sun for too long isn't good but when she is I want to make sure she doesn't get burned what is a good sunscreen I can use and any tips on having a baby at the beach? We're only there for 3 whole days.
