Pregnancy update - Week 39

I went to see my midwife yesterday and my uterus measured a centimeter less than last week which is a sign that the baby is dropping more. Unfortunately he/she was also posterior so my midwife suggested that I try more pelvic tilts to get the baby to turn (especially when labor starts). She said that in Mexico the midwives believe that babies don't like the cold so they tend to turn their backs to the mother's back when the weather is cold. My midwife has noticed in her own experience that there tend to be more posterior babies in the winter time. I suggested that maybe I need to walk around the house with a heating pad on my belly...
