Whenever you pick up or hold your chin you want to be gentle, but hold him in a way that he is secure and won't fall if he starts to squirm a little. If a chin feels like he doesn't have something stable to rest on or that makes him feel secure, he is more likely to wiggle and squirm. Always have your hand palm side up under your chin's feet, while your other hand is either under his armpits or cupping his back. Hold the chin close to you, and this will make the chin feel secure and give you control should he start to wiggle a little.
