Have a look at the Lancet's 2008 Maternal and Child Undernutrition Series. I am pretty sure I read there that there is no significant difference between the HIV-free survival rates of children weaned suddenly at six months and those who continue to breastfeed.  Transmission rates are 1%/month of breastfeeding in mothers who are receiving pharmacotherapy - lower if breastfeeding is exclusive.

Subject: HIV transmission risk higher beyond 6 months of EBF

Does anybody know why/have the data regarding the transmission rates of HIV
going UP after 6 months of exclusive BF ?  I have seen the comments made
before that long-term or anything beyond 6 months of EBF puts the baby at a
*greater* risk for transmission.  Evidently, I find this odd...
