Why does a 2 year old bite scratch and hit?

A 2-year-old may bite, scratch, or hit as a way to express their feelings, communicate needs, or explore their environment, since they often lack the verbal skills to articulate emotions. This behavior can also arise from frustration, seeking attention, or imitating others. Additionally, toddlers are often still learning about boundaries and how to interact with peers, which can lead to physical expressions of their emotions. It's important for caregivers to respond calmly and guide them towards more appropriate ways to express themselves.
