My DS is 25 months and we are still nursing (much to my surprise -- it is not at all what I planned before I had him and I wasn't sure I'd make it past the early days...but I digress).
I have no immediate plans to wean him completely but as he nurses A LOT I am finding that sometimes I really need to limit it. It's easy to set limits when we are out (I don't mind BFing in public but sometimes it just isn't very convenient) but at home it's a big problem. If I say "no," he literally claws at me until he gets one of my breasts free. If I stand up and go away, he follows me begging and pulling at my clothes. If I say "yes but for 1 song/1 story/a count of 10" he will.not.get off when that limit is reached and when I unlatch him he fights it and claws at me and so on. This little determined guy will literally nurse in any position so there is literally no position that I can assume in which he isn't trying (seriously, if I am standing he has tried to climb up my body). He will absolutely not relent until he gets to nurse and until he determines he is done or gets distracted by something else. I have tried to explain that mommy needs a little break or that he has to ask and respect my body. He does seem to get those messages as he repeats them but he seems to think that 1 second is a break and that asking means he gets to do it, so they aren't helping to actually get a break.
