Hi P.,
My heart goes out to both of you. Your son wants to please you -- and that to him, is probably more important than being totally honest about his day. Is it possible for you to call the teacher before your son gets home from school to see what color his behavior really is? That way, you would be able to praise him when he has a "green" day and when he tells the truth. It would also show him that he can't get away with fibbing on his book.
My son is an active, independent 8 yr old. He had a 1st grade teacher who loved him and he was praised all the time. He loved school and did very well. In 2nd grade, his teacher did not like him at all and he was constantly being reprimanded. I volunteered in the class every week and had conferences twice each quarter with the teacher, but nothing changed. Although she made it seem like my son had a big behavior and attention problem, it was quite clear, from what I saw and from talking to other parents, that she was a very strict teacher & definitely did not enjoy teaching 2nd grade boys. My son dreaded going to school and his behavior at home worsened. It was like he was living up to his "bad kid" label that she had given him. I finally requested to move him out of that class, but my son did not want to leave his friends, so he stayed. We survived a very difficult school year, but his self esteem was damaged. He was always frustrated & he called himself dumb all the time. [He never lied to me about his behavior -he didn't have the opportunity -she wrote notes home and called quite often.]
We started giving my child Fish Oil, Magnesium, and a product from the health food store to improve focus in the morning, and Zinc at night. He also is on a low sugar diet and eats a lot of protein during the day. This year my son's teacher is not biased one way or the other, and while he's not the star student, his teacher sees his strengths and weaknesses and she works well with him. He doesn't feel picked on & his self esteem is good. He once again likes school and is getting good grades. He has about 3 days a month when is behavior card is marked. So much better than last year!! He is still challenging at home sometimes, but reading NEW KID BY FRIDAY and 1-2-3 MAGIC has made disciplining him much easier.
(BTW, his teacher this year has 3 sons, so she understands boys. Last year's teacher had one adult daughter. I have a friend with a son in her class this year and she is going thru the same thing that we did. I'm advising her to move him out of the class. If I could go back & do it over, I would move my child.)
Good Luck and God Bless!
