sleep onset problems, children may also experience a range of
undesirable behaviours occurring during their

sleep - wake transitions, including sleepwalking,
sleep talking, bedwetting, bruxism (i.e., grinding or clenching the teeth during
sleep),
sleep terrors, and rhythmic movement disorders (rocking the entire body from one side to another, rolling the head against the pillow).
