If parents are unhappy, depressed, or worried, they tend to pay less attention to their children. So, odd as it might seem, their children learn that they have to be naughty or noisy to get any attention from their mum or dad. If you have never said what is allowed and what is not, children may simply learn they can get away with being noisy and boisterous, even when it is not what you would like. It can help both parents and children to have some simple, clear rules about this. A few children become noisy and irritable when they are given certain medicines especially medicines used for asthma, travel sickness and to help them get to sleep.
Some children do seem to react to certain foods by becoming restless and irritable.
If it does happen, it doesn t last long. Children with ADHD will be very restless, unable to concentrate for more than a few minutes, and may behave recklessly. No one should be given this diagnosis until they have seen a specialist. The first thing to do is to make sure you have time to spend with them on their own. Then they will know that you are interested in them and concerned for them.
