Deena, I found during my first pregnancy (not nursing, obviously) that my = nausea was mild. I was extremely hungry and very sleepy. During my = second and third pregnancies which occured when my first child was 13 = months and my second was 22 months, I had terrible morning sickness. = Actually, it was morning sickness with #2 and evening sickness with #3. = I did not really attribute it to nursing at the time. Both my older = kids weaned about halfway into my pregnancies. In pregnancies 2 and 3 = the nausea and vomiting lasted much longer than in #1 (16-18 weeks vs = 10-12 weeks). Was it the breastfeeding that made it worse or was it = because I was tired from caring for my older kids or the increased = stress a second and third pregnancy placed on my body. Who knows. :-) Kathy Koch, LLL Leader Oak Harbor, WA
