May-Treanor has been fairly quiet about her second pregnancy, but has given her Twitter followers a small peek into her life as a soon-to-be second-time mom.

“Could this be the last day of monitoring???? #ComeOnBabies,” she wrote alongside a Nov. 6 snap, showing a device strapped to her bare belly as she lay in a hospital bed.

“Monitoring for the day done … 34 weeks,” she captioned an Oct. 5 photo featuring her baby-bump-laden shadow. “Can’t bend to wear shoes but it is ok. #PregoProbs

May-Treanor and her husband, a 41-year-old former professional MLB catcher, tied the knot in January 2004, welcoming their daughter in June 2014. Malia’s middle name was chosen in honor of May-Treanor’s late mother, nationally-ranked tennis player Barbara May, who died of cancer in 2002.

The athlete announced she would be retiring shortly before she and teammate Kerri Walsh-Jennings took home their third straight gold medal in beach volleyball at the 2012 London Olympics.

“We both want to start a family,” May-Treanor said of herself and Walsh-Jennings in 2008 after winning gold at the Beijing games. “We need to slow down and breathe a little bit, focus on our families.”
