I second the saying that breastmilk is so sweet it doesn't really matter whether vegetables come before fruits when introducing solids in babies. In addition, breastfed babies have already experienced different tastes from hsr mother's breastmilk. They are more likely to enjoy the different tastes of solids and be less picky.
Fruits were DS's first foods, but he still loves food with very mild taste (e.g. plain rice).
