Effects on baby while breastfeeding during your period?

My baby girl is just about three months, and I just had my first period since I got pregnant (she's sleeping long nights and gaining weight perfectly). On my two worst days of my period, I noticed a tiny tinge of pink in her diaper. I have heard of this happening in the very beginning, when the female baby is reacting to the hormones from the mother's womb. Has anyone heard of this happening while the breastfeeding mother is menstruating? I have a doctors appointment this week to make sure it's nothing serious, but since it has only happened while I'm menstruating, I'm not overly worried. Please only respond if you have heard of this before. Thanks!

I just got a call back from my doctor, who said it was perfectly normal, and related to estrogen withdrawal!

The only problems we had was that my supply dropped a little and (apparently) my milk didn't taste as good.

The only thing it can do is change the taste of your milk, Baby may not like it. That is it.

It shouldn't be happening after the first week.

If I had to guess I'd think its probably yeast, mom is more prone to yeast infections just before her period, yeast overgrowth is passed to baby takes a few days to develop and then baby has some minor irritation.

A female infant may have a small amount of vaginal bleeding during the first week after birth. However, further vaginal bleeding in an infant requires an evaluation.

Answer:

During pregnancy you baby is exposed to high level of hormones. When the hormones are withdrawn (due to birth of the baby and placenta) your daughter's body can respond by producing a vaginal discharge. The white discharge and the bloody discharge are generally normal. This discharge is seen during the first week of life. The discharge continues past one week of age, or increase significantly in amount you should contact your daughters health care provider.

A small amount of vaginal bleeding in the girl between the age of 5 and 10 days is normal. It is due to maternal oestrogens and is not related to haemorrhagic disease of the newborn.

Normal bleeding during infancy
Within the few weeks immediately following birth, some newborn girls will experience a small amount of bleeding from the vagina. This is entirely normal and occurs as the level of the mother's hormones in the baby's system gradually decreases. The result basically is the equivalent of a tiny menstrual period.

This type of vaginal bleeding usually lasts less than a day and is not painful. No special evaluation or treatment is needed; and in fact, such bleeding during infancy can be somewhat reassuring, because when a baby girl's body responds in this way to the drop in hormone levels, it's a sign that her system is working properly.

The important thing to keep in mind is that neither the presence nor the absence of bleeding in these early weeks is anything to be greatly concerned about. Either situation can be considered normal.

Vaginal bleeding after early infancy
From early infancy until a year or two after a girl begins to show signs of breast development as well as other signs of puberty, bleeding from the vaginal area is not normal. While quite often the cause of vaginal bleeding is not serious, it always warrants a visit to her healthcare practitioner for evaluation. A visit to your pediatrician or family doctor is probably the best place to start.
