Lol Nickers, Betsy booby ROFL, now why didn't I think of that, lol. I got the recipe from a thread in Breastfeeding/bottlefeeding forum.
It is 1 litre of milk skim, 1 cup of skim milk powder, and 1 cup of activite.
I actually used full cream milk and milk powder as it was all I had.
This really worked for me. And it tastes yummy. I have three glasses a day.
