Many fears of infancy extend to the toddler years. Fears increase after 2 years, because toddlers are aware of more things to fear. Toddlers often fear monsters, animals, darkness, "bad people," injury, and startling noises. Toddlers tend to act out their fears in play rather than talking about them. Adults should never tease toddlers about fears, but avoid or limit TV consumtion, which often limits the things that toddlers are aware of, limiting what they can fear.
