That is a running theory with which we do not agree and I will tell you why.
In order to develop our Happymamis, we study breastfeeding as a whole.
Breast milk ejection, outflow at each stage, baby’s suckling, baby’s needs …. And from there we developed our flows.
So if you have a 4 month old baby and you put him/her on a 2 month old baby flow, what is probably more at risk is that your baby will reject the bottle .
That is why our recommendation is that you take the flow that corresponds to your baby’s age, and follow the guidelines that we will give you when you make your purchase so that your baby takes the bottle without affecting your breastfeeding.
