If they are struggling, panicking, squealing, letting out "stress poos", then they are not happy with the way they are being held. I would just say just see how he's acting. If he seems uncomfortable or restrained, loosen up a little bit. Having a blanket on your lap to run around on helps.
As for actually breaking something, I would just avoid anything that would cause harm. I honestly won't go into comparing hedgie bones to other breakable objects. Grabbing a foot and holding on while hedgie tries to flee won't hurt him if you make sure not to twist or bend anything the wrong way.
Sorry, I hope that makes sense, haven't come across that question before.
