Congratulations on your baby. The first few days after birth the child is still under the influence of the mothers hormones (which are in abundance during pregnancy
and childbirth). Due to this, the vagina secretes thick mucus and this may appear as 'white skin'. It will resolve with time. Also sometimes these hormones may cause the breast of the newborn girl to secrete some fluid - called 'witches milk' in the old days. This again will resolve with time.
Please be reassured and contact your doctor only if it persists beyond 2 weeks
