"Thought we'd be a few hours, turns out we're staying overnight," Michael wrote in an update to fans.
But Michael made an uncomfortable stay a little more bearable with a makeshift bed on a lounge chair, and even bought Lucius a new onesie.
Poor Martha cannot catch a break! Five weeks into her pregnancy with baby Lucius, the mum was diagnosed with a rare condition called hyperemesis gravidarum.
"Which is basically severe chronic nausea and vomiting with no relief. It is like 24/7," she previously revealed.
"I literally did not get out of bed for two months, I was so sick. I could not eat or drink anything. There were days that I did not even get up to pee."
But after an unexpected hospital stay, the family of three have finally returned home.
"Had approximately 34 years worth of antibiotics pumped into me and three days of hospital food," she revealed on Instagram.
"Ate a bowl of fennel in the bath, sipping on coconut water and already feel brand new."
