Girls, who knows how to combine and give in one feeding dose of Friso Gold and Friso WoM? The thing is that we have regurgitation after each feeding (1-2 tablespoons), and a mixture with a slight reflux effect is needed, completely switch to Friso WoM is very expensive (a bank of 1800 costs us), what scheme do you need to mix these two mixtures into one dose? Who knows, please answer ?
