Maddie Brown Brush is getting ready to meet her little girl!

The Sister Wives star, eldest daughter of Janelle Brown and husband Kody Brown, shared a shot on Instagram Sunday of her cradling her baby bump and reflecting on the countdown to her third baby.

"The mom-t30 weeks and some change! 🤰 I'm not entirely sure where the last 30 weeks went, but ready for the next 10," she wrote.

"Stuck between a place of panic because we have so much to do in the next 10 weeks," the soon-to-be mom of three added. "Also hoping maybe for maybe a short 8 weeks so we can meet this baby girl and I can have my body back. 🤣"

Maddie and husband Caleb Brush are already parents to son Axel, 5, and daughter Evie, 3.
