It always irks me when people list the benefits of breastfeeding and somewhere near the top is "it's free". Those extra calories (300-500 per day) that your supposed to consume when ebf are not free. I think all things considered I probably spent more on cake extra food than I would of on formula.
I do think there's lots of benefits, DS is nearly 8 months and I'm still BF, I just don't think this is one of them.
