You have described a child that has a LOT of fear in his life.

You should NEVER under ANY circumstances bite, pinch, or hit him - even if it's "softer"!!!!! All you're doing is teaching the child to continue the unwanted behavior. How terribly confused he must feel.

He is TWO years old...he should have a safe, loving, secure, gentle environment with a bottle if he wants one (I do not understand why the rush to get him off the bottle?), warm blankets to snuggle with, love, love, and more love. And firm, patient, calm, gentle discipline when necessary. He needs to be gently taught to verbalize his feelings and thoughts and he needs to be heard.

Treat that toddler as you would want to be treated. Exactly, and without exception. He desperately needs consistency, love, gentle patience, and nurturing.

I strongly encourage you and your husband to take your little one to a play therapist so he can learn how to identify and express his feelings, emotions, and thoughts.
