I'm currently bf DD who is 20m (morning and night, and naptime on days when I'm at home). I'm now 8 weeks pregnant with DC2 and had my booking-in appointment at the hospital today.
I happened to mention that I was still feeding DD. The midwife told me that I would have to stop. I asked why. She didn't really seem clear - mumbled various things about it interfering with pregnancy hormones, affecting the blood supply to the baby and my body needing to focus on the pregnancy. I asked if she could direct me to any studies on this but she couldn't.
I may choose to wean DD before DC2 arrives to try to reduce jealousy, etc. I understand that children do sometimes self wean during pregnancy. I would however like to be aware of all the facts, as far as possible.
I have a couple of friends who have successfully bf during pregnancy, and then tandem fed, so I know it is possible.
However, I am interested in the medical side of it and I'm wondering if this is something any of you have looked into?
