Check the bag
Lunchbox, gym kit, the homework book, the water bottle, all of it held in the head at once while the clock ticks. It is exactly that mental list that cracks when stress rises. The pictures below move the list out of the head and onto the wall.

About this visual support
Packing the bag right means keeping a whole list active in the head at once, and that very ability is fragile in the morning when time is short and everything has to happen fast. A child may well know what should go in, yet still drop half of it because working memory cannot hold every part while moving between rooms.
Pictures take the load off by moving the list outside the head. When each item exists as its own picture, packing becomes a matter of looking and ticking off, not remembering. The child can compare picture to bag and see straight away what is missing, without an adult reciting the same things every morning.
One concrete tip: hang the picture list by the front door, not by the bag, so a final check happens just before leaving, while forgotten things can still be fetched. Put the most often forgotten items first in the row. If you want the list to change with the day, gym on Tuesday, swimming on Thursday, you can set up variants in the Routined app.
