The best thing to do is to have a
ball and
roll it
towards and away from your baby, which will encourage your baby to
keep his balance while moving forward and back, and while moving from one side to the other.
As you lift each toe, try to
keep it pointing straight ahead, not pointing
towards the other toes, and be sure that the
ball of the foot stays in contact with the floor, as it's easy to cheat by
rolling your foot rather than lifting your toes.
