Hiya, his dad has adhd, but i do understand this could just be him, and im not trying to self diagnose it's just curiosity as to whether my opinion will be he could develop it or not. I know it's wayy to early days to know. Just i recognise similarities between him & his dad, ie... needing 6/7 hours sleep instead of up the average of 12 for child of his age, he has same health issues as his dad, and he now has same appetite as his dad, two full meals, a lot of milk, a lot of juice, and 2/3 full yogurts a day (he is on 91st centile for height, and just over 25th centile for weight so long and thin) he is slowly putting on weight and is classed as still under average weight x
