I've been seeing an ad for Minbie teats recently and I feel that the claims being made in the ad are not the sort of thing that MNHQ should be promoting.
The ad claims that their teats are "the closest teat to breastfeeding!", which can't possibly have any actual evidence for it.
Baby Milk Action have had concerns about this company as well. You can read more about their concerns here:
