Wipes, wipes and more wipes, preferably the non-alcohol, unfragranced ones. You can also use nappy liners and warm water.

I am anti-powder for respiratory reasons, and I am also very anti-Johnsons...their bedtime bath that supposedly contains lavender and chamomile is just synthetic chemicals made to smell like that, nothing to do with the actual plants. I should admit though that I am an aromatherapist and make my own baby products, so I am biased 8-[ !

For baby massage, you can just use good old extra virgin olive oil. A lot of commercial oils contain petrochemicals and are more expensive anyway.

I guess I would say to just get some wipes and and a baby wash for bath/hair and then wait and see if you need moisturiser or if your baby likes massage.

Good luck!
