While I don’t generally love telling parents what they can and can’t do or eat etc during lactation, there are a couple of things to be aware of that can have an impact on milk supply. This list isn’t exhaustive and you should always check with your primary caregiver or lactation specialist.

Peppermint - Excessive amounts of peppermint could lower milk supply in some mothers.

Sage Tea - Due to the drying properties of sage and infant gut hypersensitivity, it is recommended to avoid sage either as tea or in foods.

Pseudoephedrine, otherwise known as Sudafed, is used as a decongestant, meaning it is used to dry up mucus. In women with marginal or low supply, this can cause further milk loss and it is generally recommended to avoid it while breastfeeding for most breastfeeding parents.
