whatever you buy, read the INGREDIENTS box on the back.

Perfume
SLS (cheap foaming agent)
parabens
they are the main contenders for aggravating skin like your dd's.

so avoid products, with those words (or parfum) in the ingredients list

Miessence
burt's bees'
cherub's rub (i found that at a shop called Eco-lateral, and i've seen it online too)

organic care in the supermarket, i'm careful with that one, after discovering so much perfume, in their "soap on tap" (the green tea one) that i coudln't use it - could not bear to have it in the house, was SO overpoweringly strong. but have no problem with their hair products. And their detangler for kids is very full of perfume too. so i think that company is a "mixed bag".

maybe google "organic bubblebath australia" and see what you get?

i love the SUKIN range, but haven't noticed a bubblebath. Also MOO GOO.

I wash us with goat's milk soap, no colour, no perfume, very simple (much cheaper, buying the no name goats milk soap at the health food shop, 10 for $12)

Once i found out the main irritant culprits, i went thru the bathroom cabinet adn threw out TWO bins of products. SO MUCH of what i had (at that time), had parabens, perfume, SLS in them. The difference has been amazing. well worth doing.
