Parents...any LO currently drinking or feed on Nan Pro 1 and thinking abt switching to other brands? Any particular reason for switching?

hmm.. I think each baby will react differently to different brands (e.g. due to taste or perhaps baby is sensitive etc). I have a friend who supplemented her breastfeeding with formula. She had to try a few different brands before finding one that her baby takes to. For her, because she only started having both breast milk and formula milk when baby is past 6 months old, she was able to get samples from the various brands. If I'm not mistaken, most companies do not offer sample for stage 1 formula (but you can try contacting them to request for it I suppose). Not sure why you may be considering changing, but I've heard that NAN is quite close to breast milk. Similac is another popular brand that my friends recommended trying. Hope this helps!
