My son is 28 months and still nurses it is variable I work 2 12hour shifts a week at night so he goes a long time between some nurings but I never started my period. I even stopped birth control ( I was just on the mini pill) for 3 months and didn't get pregnant. I am thinking I might have to totally wean him at 3 in order to get pregnant. Any one have this problem? Three is still a ways off and I think once summer hits he'll probably be so busy playing outside he won't ask to nurse so often and maybe he'll wean himself. I had thought from hearing from others that he might just wean when I got preganant, but I guess that might not be possible.
