Yeah, please don’t try and guilt new moms into feeling bad if they have a hard time breast feeding, or can’t, or even don’t want to. Formula is perfectly fine and really makes the whole first year of child rearing way way way more manageable.
The overall outcome is more important than any one factor. This applies to any activity, opportunity cost is always looming over us.
It looks like that applies to the studies too based on the parent's link - looking at just one factor finds some differences but then there's no overall difference by age 5. So that's definitely something I'll pay more attention to when the next headline rolls around.
Breastfeeding after that is way way easier than pissing around with powders and bottles.
