I would go get it checked out. Probably just early developement. Are you having her drink only organic milk and meat products. There is a huge concern, and rightly so, of hormones in dairy and beef with too many of our girls developing early, having hormones disrupted from their normal cycles.
On another note, you need to also be very aware of the dangers of the Gardasil shots. These are causing serious problems in our young women and I personally am not having my daughter near them and they are promoting them with girls as young as 9. Is your daughter planning on being sexually active before the age of 14? Didn't think so. It has not been proven that HPV is the cause of cervical cancer and the main thing to remember about HPV (there are many types and the vaccine may cover just 4 of them and it may only be effective for five years - they just don't know yet) is that in over 90% of the viruses are taken care of by the immune system. If you get an annual pap smear, the test will catch any cervical cancer and it is easily treated. The problems that are happening is beyond the girls fainting or having soreness at the injection site. There have been over 15,000 (from six months ago) reactions that also include seizures, genital warts, chronic fatigue, paralysis, severe headaches (too much aluminum for the body to handle) and death. There has been a stronger association with our young women having severe problems when there are any allergies anywhere in the family.
So just say no to any Gardasil shots. Let them use someone else a bit longer as guina pigs. If you have the doctor /nurse ask you why you want your daughter to get cancer (nice huh? happened to us) just reply that you'll wait. It is not mandatory AND it should never be given at the same time as any other shot. With any vaccine, ask to read the package insert when you are told there will be shots. Take the time. Please.
