I live in the UK and am visiting my family in the US, and my brother just showed me these Camilia things they use for their baby for teething. In these single dose plastic tube things. Do you all use these? Is there something else similar I can look at as well? I'm just thinking, if you can buy it not in single doses, it would be cheaper. In the UK we have these little packets of powder that's some sort of chamomile, I think it might be similar but they don't seem to really work.
