Someone mentioned baby stuff.... I dont use any of it, at all.
I use plain old olive oil (in the brown bottle from the chemist, all natural pure iol).. for bath, hair, moisturiser everything. They dont get any products till its time to wash longer hair.
Its cheap, natural and its what they use in the good hossy's too..
My sister had a bub last week & when we went to visit her in hossy they had signs up saying they don't use anything - just water. I was impressed, lol.

We use Gaia baby shampoo.
