She doen t have any reaction when we touch the lump. The baby is now 9 pds 5 oz. The delivery had bit of issues, my daughter s contractions were long and long wait inbetween, they gave my daughter something to make her contractions shorter and faster. The baby was born with her head blue and blue spots on her forehead and gone after 10 days.
