Hi Claire – in some cases, early puberty is normal. In other cases, a child should see a doctor so I would recommend speaking to an endocrinologist first and foremost if you’re concerned.
From a functional perspective, I speak a lot on social media about endocrine disrupting chemicals. These are ever so present in our day to day lives, which are definitely impacting children’s hormones as well.
Going through the Beginner’s Health Roadmap and beginning to “detoxify” your environment at home is always recommended. You may have seen this post of mine on social media. You can also find more info in this handout on toxin avoidance in the Resources.
