oh dont worry i dont find it offensive :) the longest ive breastfed for is 2 months (1st baby) and funnily enough i concieved a girl shortly after stopping! i think you are right, there are women who exclusively breastfeed and get lots of boys close together, but as you say its so draining and exhausting especially at first that its got to be pink friendly.
i admire anyone who can do it and stick at it because honestly i just cant face it.
