Soy based milk is more expensive than normal cow's formula. Unless ur bb could not take it. And they do not offer in bigger tin. Max is just 900g.i'm in dilemma. instead of choosing the right milk powder, i'm now trying out the different teats for 1 month plus old baby. she seems to have hard time to suckle. btw i bought a soy based milk powder to try feeding, i don't know if it's good. any comment on soy based milk?
