When a system misbehaves consistently, you stop attempting to force the system to behave and instead sit back and examine why it is misbehaving. If your wheel doesn't like to roll downhill and keeps veering off to the side, no matter how even the wheel is.. sometimes it's the hill.

One of the Montessori practices I'm a big fan of is observation. Quiet almost secret observation of the child. Ideally the child isn't aware you're there and you merely observe them act freely (in a safe environment for the child).
