Reese WitherspoonSoon-to-be mommy of three Reese Witherspoon is expecting another baby this fall but the little guy or girl is trying to arrive early. Despite her September due date, the Oscar-winning actress is holed up in a hospital under the observation of doctors. Everyone on deck is trying to prolong the baby’s womb time — and for good reason.

RadarOnline reports that Reese’s medical team is trying to prevent an early labor so that she’ll carry the baby to term. Since even shaving off a few weeks at the later end of pregnancy can impact a baby’s development, the actress is clearly in good hands. Meanwhile, supportive husband Jim Toth is having a bit of a freak out:

“Jim is really worried about the baby. He’s a first-time father so this is all really new to him and he just wants everything to be okay,” the source revealed.

“He’s a bundle of nerves. Meanwhile, this will be Reese’s third child, so she’s been through this before and she’s trying to keep him calm.”

Leave it to a birth veteran to keep it copacetic in the maternity ward.
