I'm happy with the Aromababy range. Reason - mainly coz its quick & easy to purchase (available at our local pharmacy) The baby wash doesn't smell because it doesn't have any fragrance or essential oils. The quantity of essential oil needs to be really really tiny for use on babies, and isn't really recommended.

I've used beauty & the bees soaps & belly balm, but haven't used anything on the kids.

Synthetic fragrances can be an irritant, but as Bath said, so can essential oils. Altho the oils commonly used are lavender & chamomile which should be fairly safe if in very very small quantaties.

I'm not that fussed whether they are organic or not, just so long as they are plant based ingredients and not petroleum based I'm happy

ETA: Oh I meant to say I like Aromababy baby wash too coz there is no surfactant (not even plant-derived) so don't expect too much lather (people are obsessed with bubbles LOL). Surfactants are what dry the skin out, stripping it of natural oils.
