Regards from me and my son!

Tnx for the answer dear Dr. Sameer! Sorry for the confusion about posting my questions - I am not sure weather to post them in the end of the line or as a new post.
My son is very lovable, sensitive and addicted to me and his grandma, listens to me (I am divorced and live with him and my mother) and his grandma (but he likes teasing her sometimes when understaning that he is irritated thus entertaining himself. But once when we lost a track of her in a big department store he got very confused and started crying for her.) and falls asleep while I am around him after reading the stories, telling me that he loves me and I respond him the same & after I say the night prayers. When I am at work in th evening around 17 PM he calls me to ask me if I would return at home soon - he entertains with me more than with his grandma anyway. He sees his father 4-3 times monthly and recently doesn't ask so much about him especailly after his dad slapped him badly on the face because he didn't want to stay with him in the market while I was shopping further and thus made a scandal on a public place and attracted the attention of a mother of 3 boys advising me to sue him. My son is very open to people, he smiles to the ones he likes and establishes connection very easily, especially with beautifully young ladies.
My son is fearless I should say, ready to experiment and sometimes even tries and licks with his tongue some not so clean objects and surfices especially if he wants to provoke and tease and attract scandalously the attention. That is why he probably doesn't respect the authorities at school like teachers and behaves sometimes like a clown in a circus while entertaining the kids. He is very difficult in eating in the morning especially. After that he prefers to eat teasted bread with butter or margarine very much, sometimes toats with butter and pepper, some dry Bulgarian sausages, pizza, soups of liver and nettle, soup of boiled beans and lentils, tomatoes, sometimes eating slices of lemon, oranges, commercial juices, not so often homemade. Probably that is why he is slim and even says that he wants to keep fit. His aversions could probably be named dislikes - he isn't very tidy with things but if he likes some of his toys very much is very caring. He forgets about the sense of possessing things sometimes. He forgets to put on slippers while going to the balcony sometimes and doesn't pay attention to term 'being clean' sometimes. At home he likes to look through books, to draw, to play with his constructors, with the computer games. When he is bored he likes to go around the rooms of the house, to rummage or to pour water in some small cups or water pistols and take them inside the room we stay or go to the balcony and talks and entertains the neighbours. Probably because his sign is Fish and Chinese sign - a Water horse.
I want to add that my son likes to drink herbal teas very much andhe also likes a small piece of Milka chocolate sometimes during the day or in the morning and also eating now and off chocolate waffers especially after his swimming courses. He also likes fried potatoes lunch time sometimes. We try to quit chips. He likes rice and whole grain cornflakes and popcorn.
So please advise me what remedy to use in that case. I will appreaciate your facilities very much.
Thank you in advance!
Warm regards: Eli
