I came across this article and thought it was very interesting in what is all takes to formula feed compared to breastfeeding. I was also surprised to learn that formula fed babies consume 30,000 more calories than breastfed babies by the time they are 8 months old. The article says this is a factor contributing to childhood obesity. Never force a baby to finish a bottle — no matter the substance. Babies stop eating when they are full and naturally do not overeat (if we could only carry this trait with us to adulthood). This is even true as they enter toddlerhood. A child’s stomach is only as big as their sweet little fist.
