It should tell you on the pack. We used to use this but we now buy the aptamil reflux and it’s already in the formula xx
Start off with half a scoop and then increase by half a scoop per bottle and see what ur baby is willing to tolerate. Most people use half of what there baby drinks so ur baby has 4oz so 2 scoops however just go off ur babies cues. My baby won't have more then 1 scoop in his bottle and he's on 9oz bottles. Also get bigger teats because if its thicker it's harder to get though size 1 teats but obviously that depends on how much u add. Only add when it's room temperature don't add when it's hot and remember to let it sit for a minimum of 3 minutes before u give to ur baby however it will continue to thicken over 15 minutes so bare that in mind when ur adding a load of scoops xx
My little girl is on 4oz bottles and I put in 3/4 full of a scoop. It says 1 scoop per every 3oz! I add it into my milk pots when I make her formula pots up and add into the cooler nuby water xx
