Calories/day for BF Mom?

[Grant-D]

I have been trying to be 'good' for a couple months with no real results. But I have been too scared to really limit my calories because I am still breastfeeding my 4month old and obviously want to pick my supply. Any of you do this and what was your calorie range? I thought sticking to the average 2000.
I do cardio 5 time/week and full body strength 2/week. So I figure the diet needs to change in order to actually see results.
Advice ladies?
Thanks!

Have you tried to drop the cals by 100?

Or perhaps add in one more day of full body training?
