Hi my 3.5 year sometimes goes extremely hyper bouncing off the walls, going way over the top with things, she ends up hurting people and doesn't listen when ppl tell her to stop you have to literally push her away (gently) or carry her away. When she gets like this there's no reasoning with her. Taking away toys, timeout etc doesn't work and it almost always ends up with her having a massive tantrum as she doesn't get her own way. I've never seen a child so hyper. Someone suggested sweeteners etc but she doesn't have any really. She hardly has sweets she doesn't like them, hardly any chocolate, the odd diluted squash as she prefers milk. She was fine when she got up this morning but I gave her an orange and all of as sudden about 5 minutes after she ate it she was going crazy bouncing and jumping every where rolling around the floor. Can oranges do this?
