I was asked by one of our Lactnetters to send the text of Lisa's reply.  I
suspect that it was heavily edited, but it does make the point succinctly.

Your advice on what parents can do to enhance brain development in children
omits something that can raise I.Q., improve visual acuity and more, yet
save the family money.  It's simple, naturally: feed the baby yourself.  How
about a cover on breastfeeding?  I'd like to see that!
