I am 8 weeks pregnant and DD is 28 months and nurses 3 x in a 24-hour period: Early morning, naptime, and evening/bedtime. We recently night-weaned just because no-one was getting any sleep and I discovered that the night nursing was actually keeping her up. Anyway, I have noticed a huge decrease in supply but I think it is a combination of the cutting back on nursing to begin with and then the pregnancy on top of that. I have no soreness at all. In fact, we struggled for the past 9 months with eczema and that hurt more than anything - now it actually feels pretty good to nurse! We are gently encouraging her that she won't need to nurse much longer because she is a big girl. I would probably be okay with nursing two - but I think it is just time.
