My 10 month old pinches ALL THE TIME. It's basically his only self soothing mechanism. When he nurses he constantly pinches my breasts, chest and arms. He also pinches me when he's tired. It makes me CRAZY and it's legitimately really painful. I've tried holding his hand but he just unlatches and screams until I let go and let him pinch me again. This has been an ongoing issue as long as I can remember. You can't discipline and infant and I just keep assuming he'll grow out of it, but it's really getting to me at this point. Any magic ideas?
