Should we save our baby's umbilical cord stump?

though this may sound very disgusting for some, my mom saved my umbilical cord. For her it was the connection between both of us. She always says this, "you look exactly like your paa and this cord reminds me that we both are connected" I kept my daughter's too.. Its been over 8 months now. I kept in a cloth sewed by myself. There are no molds or anything its perfectly fine :)
