My sister who will be giving birth soon needs to know what feeding bottle brand is the most recommended to prevent nipple confusion. Can anybody suggest one?

Basta bilhin niyo ung mga wide neck ... i bought iba ibang bottle na wide neck from the very expensive one down to the cheapest(as in bumili ako tig iisang brand) it was all good nag lalatch padin siya sa akin. My LO is turning 3 months now and mix fed ako nag start nung 2.5 months siya....mas magandang iba iba ung bottles para iba iba ung ma feel nyang lambot don't stick to one baka masanay.
