I have short stairs in the house, between ground floor (where the kitchen and kid's game room are) and 2d floor (where their bedrooms/bathroom is).
For safety reasons, they aren't allowed to run up/down stairs because their preferred shoes make it too easy to trip on the stairs.
The kids are perfectly well aware of the rules (they are 6/7 YO) and generally follow them well.
But when they play together downstairs and get rambunctious, they get into the "run around mindlessly" mode; and if they need to get upstairs, they run.
Are there some good approaches for fixing this issue?
Please note that standard approaches don't work at all (carrots don't help - they know perfectly well what the rules are on rational level, just forget them when being boisterous; sticks don't help either - for example not permitting to play downstairs after runnnig up the stairs).
