Why would I stop nursing when Beckham is 8 months?

1) Beckham doesn't like to be nursed in public
2) Audrey likes to poke Beckham and ask...'why Beckham bite mommy' this frustrates Beckham
3) if I put a show on and get Audrey a snack while I go nurse Beckham quick...she brings a chair and bangs on my door and cries...' I wanna brother.' 'mommy...Beckham...mommy...I wanna brother.'
4) freedom, freedom glorious freedom!
