Piggy, About 480ml. per day. The rest comes from balanced solid meals and do give plenty of water as well.
Janice, we went out to check out the milk powder for you, do not have the brand you are using. They have Nan, S26, Karicare Goat milk, these are from the 2 major supermarkets in Oz - Coles & Woolworths as well as a few pharmacies.
And thanks for sending the parcel over to me, I got them already. Thank you very much.
