Rocking

To custom the infant to get out of its own difficulties or to calm it by rocking may be to lay the foundations of a good or of a bad disposition.

To place an infant on a mouse in overhauls in order to rock it may be to lay the foundation of just a bad (not good) disposition since infants have neither the motor skills to play on a toy like this nor do they have the intellectual skills to realize how disturbing such play may be.
