<human>: What are the best hats for a baby?
<bot>: The best hats for a baby depend on their age, size and activity level. For newborns, a light-weight hat with a wide brim is ideal to protect them from the sun. As they get older, you can start introducing hats that have more features like ear flaps or chin straps. If your baby likes to explore, a bucket hat may be a good option as it will keep their head cool in hot weather.
