Uh warning - babies typically don't like the loud noises of fireworks. Sometimes even the calmest baby turns into a screaming banshee when fireworks are miles away. The sounds are very jarring and scary to babies. Although my sister-in-law had a baby who slept through it all one year...
Good pont....though Katy slept through my trial run early this morning, so maybe she's in the 2% group....
