Science is not a choice. You do t get to chose studies lol thers just more studies showing benefits of breastfeeding and that's a fact.

Well it’s proven to be worse than breast milk which kind of implies that it IS a bad choice

there is research suggesting that they are more intelligent and less prone to certain diseases.

There's a clear scientific evidence showing that breast milk IS better for a baby than formula. The formula is next best thing and should be used when women can't breasteeed. If a women can breastfeed then the only resin for choosing formula is convenience ( read egoistic mother)
