you should be very careful of putting a child on antidepressants at this age, as some of these meds have not been tested on children, and have been known to cause suicidal tendencies in kids. i have a 10 yr old adhd/ nld - non verbal learning disorder child who is on prozac 10mg, because he was said to be way too anxious on stimulants, but now off stimulants md still has him on it.......prozac has been tested on children, my son was taken off stimulants due to anxiety and other side effects, while the prozac seemed to help his moods it causes other issues, like falling asleep at school, restlessness during sleep, hyper eating to where its excessive, excessive behaviour where he was literally was banging himself into a wall, or doing acrobatics on his bed and banging his head. i started tapering him off and some most of these have calmed down at a quarter of the dose, strattera is a non stimulant and works like an antidepresant wellbutrin but is for kids too..frontline has a series on the medicated child on www . pbs. org, you should really check this out, it is scary!!! deals with kids being on physc meds...
You would be better putting this question into the Doctor Forum for an answer on the proctocol of prescribing, Good Luck
