I use Burts Bees (from David Jones and Myer) as its mostly natural and I LOVE the smell. They have a great belly balm for stretch marks too!
I stay away from talc and use the powder that doesn't contain talc (again, i use Burts bees)
Go with what you like the smell of cause baby will smell of that!
I got a few samples of things and that was worth while!
I use a powder, a body/shampoo wash in one, nappy paste (i get that from america.. its awesome!) and thats about all.
I also got a medi honey ointment thing that is awesome for rashes.
Keep it simple cause you get lots of samples from everywhere and you will develop a favourite soon enough.
hope that helps
I will be interested to hear what people like cause I get sick of the same smell!
