What if you find a discharge in your baby girl’s diaper? Depending on your baby’s age and the characteristics of the discharge, this can be normal or a sign of for example an infection.

Mom’s Question:

I was cleaning and changing my nine-month-old daughter’s diaper and noticed a thick yellow mucus discharge from her vagina. Is this normal? I only have boys, this is my first girl.

Baby Helpline:

Reasons For Discharge From Baby Girls’ Vaginas

I wouldn’t say yellow mucus from a 9-month girl’s vagina is completely normal. If it continues, you should take her to a doctor to have her examined.

Female infants can have a discharge for different reasons:

  • For very young baby girls (younger than 3 months old) vaginal discharge is often related to hormonal changes during and after childbirth. For a baby as “old” as 9 months, hormonal changes are not a relevant explanation, though.
  • At 9 months, the discharge may be due to some infection.
  • Another possibility could be if some little piece of paper or something else is stuck in her vagina and causes irritation. If she has been crawling around without diapers, then theoretically she can have sat down on something that got stuck. (Far-fetched, maybe, but strange things do happen.)

You write that the mucus is thick and yellow. That does point to an infection. Even more so if the mucus is grainy. If it would have been like egg-white, you probably wouldn’t have to worry at all. If you notice discharge several days and it seems to increase, that is a reason to talk to a pediatrician.

Other reasons to talk to the doctor are if the discharge smells bad or if you also find blood in the discharge. Also, if your daughter appears to be ill in any way or uncomfortable, of course consult her doctor.

It is very possible that she will be fine and it will go away on its own. You may want to take her just to get checked out by your pediatrician to be on the safe side.

Hope she is better soon,

I just noticed the same issue with my 7 and a half-month-old little girl. I plan to take her to the doc on Monday. But I wondered what you found out about this with your daughter. Thanks for your feedback.

      Hi Kanchan,
      The best you can do is visit a health nurse to have them check your daughter. If something is wrong, they can help you with next steps.

          Hi Lorenz,
          A pale yellowish discharge may very well be completely normal, but to be on the safe side, I think you should take your daughter to a health nurse or doctor to exclude any infections.

          Does your daughter have any signs of diaper rash?
