Is there difference between friso stage 2 and dumex stage 2? LO drinks only 170ml friso. And most of the time struggling to finish sometimes only drinks half of 170ml or even less. But on dumex, LO finishes and drinks 180ml. Realise dumex is not as thick as compared to friso. there is no issue with friso stage 1. when on dumex stage 2 LO pees more than when on friso stage 1. (just switched to dumex for a try, was on friso stage 2) Any mummies care to share their views on both brands? Thanks.
