I noticed that my 3 months old baby girl has a bit of transparent vaginal discharge, is this normal? Any of your girl have the same?

Yes, it is normal for baby girls to have discharge. The vagina is self cleaning and discharge is normal. However, if there is a foul smell, it could be a sign of infection. http://www.babycentre.co.uk/x1053619/how-should-i-care-for-my-baby-girls-genitals
