Remember ADHD is all about what is stimulating to the brain and once the novelty of a new school year wears off the motivation level tends to drop too. Have a conversation with your child so you can be sure he/she has an understanding of why this sometimes happens! One of the best things you can do is ask your child what he thinks he can do differently this year. Often times this pattern repeats itself because there was never a pause to try and figure out what to do differently. This entails having a plan of action not just saying this time will be different. Ask your child if he can acknowledge when his motivation level is dipping and ask for help? Do incentives work well? Ask your child what he thinks you can do to be supportive rather than a nagging parent. Offer suggestions to your child only after he has analyzed the situation himself.
