As a due date approaches, expectant moms are usually on the lookout for labor. But the signs of preterm or early labor are usually subtler, and both babies and moms may need extra care.
"Preterm or early labor is usually less intense, so it can be a little harder to recognize," said Greenfield. "Things like having any blood or mucus, a significant increase in pelvic pressure or mild contractions that don't stop with fluid and rest are all potentially signs of preterm labor. Definitely tell your doctor if you're worried."
Despite their conventional birthplaces, the Sarke and Thacker babies and moms are healthy.
"It's so dramatic and exciting," said Greenfield. "When it ends well, it's certainly a story to tell."
