Safe and good massage oil for baby?

What is the best massage oil for baby? when consider safe and affordable. When can we buy it? Any recommendation? Will essential oil do any harm?

At our mommy and me class, they said to use vegetable oil or olive oil. Use whatever you have in your kitchen. It has to be safe to go into the baby's mouth. I know my little one puts her hands straight into her mouth and I was very comfortable using oil on her.

We use Burt's Bees apricot oil and it works great with DD (who has very sensitive skin).
