I can tell you for a fact that my Ds, who is nearly 2, can walk and talk whilst BFing. The child has a bright future in the circus, if nothing else!
These mags are trashy bollocks for thickos who get off on bosom-hoiking over boring-ass shit presented as sensationalism.
Anyway, humans lose the ability to suckle at about 8 at the most, so she won't be able to Bf him into his teens (like the mag dodn't persuade her to say that purely for the shock value, pfthththth).
People who have a problem with Bfing or extended breastfeeding are the ones with the issues, not the mothers doing the nursing. Nothing more lovely and natural to BF (if it's right for you). We have so much fun, as well as bonding, me and DS. He brings my breasts presents and all sorts!
BTW, most women who Bf beyond 6 months or 1 yr often do it very privately exactly because of idiotic notions like those expressed in the Closer comments and all too often on MN, so the real figures of how many mothers nurse for how long are totally unworkoutable.
