bbwow,
maybe u can try explain that altho olden method works and have brought us up fine n well, but new age technology n research has proven that other methods(ur method la)works even better in delivering/providing nutrient for babies. Even FM is constantly changing and its formula is very diff from what it used to be.
Sometimes oldies juz wanna stick to their tried and tested methods, without realising they are newer and better methods out there. So I guess we juz got to make an effort to explain instead of rebuking them that it cannot be done this or that way.
Imagine we make so much effort now to feed our way, next time we become grandparents liao, our kids will be complaining in the forum, that they cannot figure out why we wanna feed this n that to their kids, and why we so 'old- fashion'. Hehe
