I don't understand my son at all. He is the best worst kid ever 😂 He's such an angel most days. Knows what he's not supposed to do and actually does it. I can even leave him long enough for a short nap most days. He will even entertain his sister so I can wash dishes. Then other days he's cussing, hitting and screaming. Idek anymore.
