Johnson & Johnson Lavender & Chamomile Baby Powder is one product I would definitely pay a little extra for.
The lavender scent soothes the baby, and caregiver too! The powder is gentle, and even though some hospitals recommend not using baby powder, people around the world have been putting in on their babies for a hundred years with no safety issues I know of.
Anything lavender is good. French botanical specialists have long praised its comforting properties and it is available at your KMart.
