Kids with ADHD can have trouble managing their time and prioritizing their activities.
One way to help them stay on track is with a checklist.
For instance, you might have a list in their room for getting ready in the morning. Get dressed, brush teeth, find your shoes, etc.
You might put another one near the door they use to leave the house, reminding them of backpacks, lunch, permission slips, boots or mittens, etc.
For very young children, lots of pictures and colors work well. You don’t want to hide the intention of the list, but looking at a picture of shoes triggers the ADD brain faster than reading “find your shoes”.
For older kids, I would still add in color and pictures – again, the brain picks up more quickly – but of course try not to make it look juvenile.
Once you have your checklist you can use it to see how much time each task takes and where your child might be having the most trouble. Maybe your son is being distracted by the TV or your daughter is taking too long to find what to wear.
Once you’ve got a better idea of where the problems lie, you can take steps to correct them.
