We suggest when first ordering trying a bundle, so you are able to sample 2 or more products to see which one works best for you. If you do get a bundle, we recommend trying one product at a time for at least 5-7 days before switching to the other blend or combining product.
When trying herbal supplements, especially to increase milk supply, there is not a way to know before hand which blend will work best for you. We encourage you to reach out to a lactation consultant if you have supply concerns, the support and education they can provide is crucial.
Also remember just because something is natural doesn't mean it is alway safe, botanical remedies are not a "one size fits all".
