Okay, here is what has happened with me. I'm still nursing DS at 26 months.
At 21 months we had gone through a phase where he was attatched to me ALL NIGHT LONG. Literally (for a month!) At first, I think it was teething, but then turned into a bad habit. So after a month of that, I refused to nurse one night when he woke up. The next night he only woke up 1 time (that was a first!!!!) I think that triggered something, because I had sore nipples for 2 weeks, then I had one day of just a little bit of spotting.
My next cycle was 74 days later. I had a "normal" period. I also had sore nipples for 2 weeks. That was the end of January. I started charting in March, and was able to tell when I ovulated. Again, sore nipples for 2 weeks, and another "normal period. That cycle was 55 days. My last cycle was 47 days.......so it is getting better. I've tried everything to get pregnant. I've been taking mega pre-natal vitamins, extra B6, extra Vitamin A, and I even tried robitussin cough syrup. But my LP has been too short, only 9 days.
So, 2 weeks ago I started night-weaning. It has gone very well. I'm hoping this is the month!!! My goal was to have 3 years spacing between children, so now that DS is 27 months old, it would be just perfect. I originally wanted closer spacing, but have done a lot of research, and have come to the conclusion that 3 years is just about perfect. Easier on the children, and the mother. And I need things to be as easy as they can be!!!!!
After having done all my research, I've really felt that 3 years spacing is what God has intended for me. Although I'm not a very patient person, so when I got my cycles back, I was a little too anxious. Like my Doctor said last week at my yearly check up "When God wants you to have a baby, you'll have a baby." Unusual advice from a Doctor, huh? Well, he's Catholic, and has 10 children of his own, and does not prescribe birth control, other than breastfeeding
Good luck, and you can pick my brain if you have any more questions.
