It's probably fine for your baby to see fireworks -- though it's best to be prepared for any reaction. Some babies may be mesmerized by the lights and colors; others may be frightened by the loud noises and crowds of people. It's always a good idea to have an escape plan in case your baby has the latter reaction. As far as safety goes, while repeated exposure to loud noises can be harmful to anyone's hearing, one night of fireworks isn't a problem. But you can minimize the noise by toting your baby in a carrier and covering her ears to muffle the sounds during the show. It also helps to sit as far away from the display as possible.
