Hi,
The best nipple preparation you can do during pregnancy is educate yourself about breastfeeding! If you think you get a lot of conflicting information while you pregnant - it's only just beginning! Gets much worse when you have the baby.
When you join the Australian Breastfeeding Association you will get a free copy of their book, "Breastfeeding Naturally" and many groups run breastfeeding classes. This is one of the best investments a pregnant mother can make to ensure their breastfeeding experience goes smoothly
Warm Regards
Barb
