There are a lot of factors to consider, and the decision should be revaluated as the child gets older and circumstances change.
What is the situation like in school? A lot can depend on the teacher, can the teacher manage and teach the child effectively without medication. Some can and some can’t, a child who gets a teacher who can’t may lose a year of learning. What is learning like at school? It is a real struggle to pass, learn new concepts, achieve to potential, stay on task etc?
What is behaviour like at school? Is the child being suspended a lot, at risk of expulsion, in trouble all the time?
What about socially? Is the child making and keeping friends? What about emotionally?
And how do you feel you can cope at home? With chores, homework, following instructions, sibling interactions and behaviour?
