At this time, your baby may be spending a lot of time upside down. This "head-down" position can be more comfortable for your baby because of the pear shape of your uterus. It's also easier to give birth if your baby's head comes out first.

  • You'll notice more movement or less movement at certain times of the day and night.
  • By the end of 36 weeks, baby's skin is smooth. The arms and legs look chubby.
  • If your baby is born after week 36 of pregnancy, the chances of healthy survival are very good.
