A baby corn snake is a bit like a shoelace - though my personal recommendation, if you're worried about how wiggly a snake might be, is to go for a 'grown on' hatchling - one that's a few months old rather than a brand new baby.
The big thing to keep in mind is that they think YOU are going to eat THEM... they don't have any interest in hurting you, and if you handle them gently and quietly, they learn that you're not going to eat them - and don't wiggle nearly so much.
