LO is 17 months old and for the past month or so anytime her belly is exposed she digs and digs at her belly button, and sometimes even down on her lower stomach. She does it so much that it will be extremely red. She spends most of her bath digging at herself, I have to constantly tell her no and move her hands away. I don't know if this is a curiosity thing or what but I have to keep a onesie on her at all times, even when changing her diaper she will do it. Does anyone know why she could be doing this and any tips on how to get her to stop?
