19 month old DD has had a slightly odd habit virtually since she was born. She gets hold of your hand, back of your hand facing her, and digs her thumbs right into it. She pushes all the muscles/ligaments in your hand from side to side and kind of ‘pings’ them. It’s so painful!
When I take my hand back and don’t let her do it, she does it to her own hand and comes up with red, sore patches across the backs of her hands.
She does it mostly when she’s tired or upset. It seems to be a soothing thing.
Has anyone else had this? Any ideas how to discourage it?
