Lauren Burnham says her unborn baby has been in the breech position for over 10 weeks.
Burnham shared a photo of a newborn baby with its feet up by its head.
"This is what I imagine @babyluyendyk is doing rn. She's been breech for over 10 weeks as far as I know. Everyone send your positive vibes/prayers our way to get this munchkin flipped!" she captioned the post.
The American Pregnancy Association said breech births, or births where the baby's buttocks and/or feet are positioned to be delivered first, occur in approximately 1 our of 25 full-term births.
Doctors most often opt for a C-section delivery if the baby can't be turned head first.Burnham is expected to give birth in five weeks. She and Luyendyk enjoyed a babymoon in Bermuda this month ahead of her due date.
"Smooth sailing. 6 weeks left!" the expectant mom captioned a photo from the trip last week.
Burnham and Luyendyk announced Burnham's pregnancy in November.
Luyendyk said at the time "nothing compares" to the moment he found out he is going to be a dad.
