Antireflux composition prescribed by a pediatrician for a 1 month baby:

Sodium alginate 10g after bicarbonate 5.4 g Ca carbonate 1.6 g after saccharinate 0.25 g banana aroma 4dr, aqua Conservans ad 200ml < br/> This preparation seems to us analogous to Gaviscon syrup but when we made this preparation, the viscosity was Clearly higher than that of Gaviscon. We obtain a gel, which we believe can be very difficult to dosed and administered. How can we reduce the viscosity?
