Bullet journals are hugely popular with children as well as adults. Young children sometimes use their journals differently to adults (see below). As you will see, there is often a passion for funny quotes, a considerable (excessive?!) use of washi tape and not quite so much organising as adults.
Older children and teens will use their bullet journals quite like adults for organisation and planning purposes. Some particularly popular spreads are below.
Mood trackers are popular (and see the mental health benefits of journaling here)
And study trackers (see how to use your journal for studying here):

They are mostly fun quotes or pictures and the occasional packing list. We hear the most wonderful stories about how bullet journals are being used by younger children. They watch youtube videos obsessively and mine Pinterest for ideas to copy. Here are some of little sis's images:
