Anyone used any 'breastfeeding teas' to any effect

[Bumperlicious]

I'm thinking not so much the ones for supply but a couple suggest they can aid baby's wind. I wonder if they actually work?

If it were me, I'd give the baby fennel tea to drink (check what age you give it from).
In Germany, they all drink fennel tea from quite young IIRC. It's supposed to be fab.
