Your mom might consider asking the pediatrician whether your little brother is anemic (has low iron levels). That can be checked with a simple blood test. Anemia can often cause extremely severe sugar craving. In fact, with the doctor saying that he needs protein but craves sugar, I wonder if he hasn't already been diagnosed as anemic? If so, iron tablets can help a lot. It wouldn't happen overnight, but the sugar craving typically decreases once iron levels get back up into the normal range. However, it is also important to identify what is causing the anemia by ruling out conditions such as celiac disease.
Now clearly there are other behavioral problems going on, and I'm sure Dr. Kennedy will address that in his reply, but you want to rule out physical issues, too.
This is my parents third child, they have tried almost everything regarding child behavior management. Its just that he is so out of control that he becomes unresponsive to what they have to say until he gets tired enough to become distracted or calms down after an hour or two. As far as getting labs done. hahaha good luck convincing my parents anythings wrong. They live in their perfect happy world and now i cant even talk to them about any issues any more.
But thank you for your imput, it means a lot :)
Thank you for that suggestion, i will tell my mom about what you said :)
From a medical pespective, it would be wise to do some basic lab work to rule out that anything is amiss. If it is, it can be addressed. If not, the reassurance is important. The matter should not be dismissed with the coclusion that everything is fine. The lab evidence will tell if evrything is fine.
The behavior itself, reardless of the medical iussue, needs to be managed and your parents are not showing the requisite competence in that arena. An evaluation by a pediatric menatl health professional would be prudent. Another option is for your folks to learn and apply the techniques that Lynn Clark details in his excellent book about managing childhood behavior, SOS Help for Parents (see www.sosprograms.com).
