These were recommended by a naturopath. They didn't do much of anything for my baby. Plus, apparently since it's a 'natural product' it's not monitored very well by the Canadiam government. They apparently don't have consistent amounts of belladonna, which turns out to be dangerous to babies sometimes - it can make their breathing so slow and shallow, that they basically sleep away to death. Clearly this doesn't happen to most babies who are given this, but it's happened to enough that there's reason for concern.
