Oil massage(any oil), gives good health , skin luster, muscle tone
, good growth and development.
First of all i would like to say, you are not suppose to worry about the colour of your baby at this point of time. because its too early to predict the final complexion of your baby as it will change over the period of time.
But if you are really anxious about the complexion of your baby let her grow a bit, build her character, then there are many skin and beauty clinics you can consult regarding this.
Currently you have to breast feed your baby exclusively for almost 6 months of age.
if possible. you can get back to me with the progress in case u need further suggestions.
