Bristol Palin's husband, Dakota Meyer, is one proud husband… and one excited daddy.
Dakota took to Instagram on April 12 to share an image of his pregnant wife getting an ultrasound. Bristol can be seen looking at the screen showing their baby in digital form while at the doctor's office.
"I couldn't ask for a better person to be the mother of my children," he said. "She's the most amazing woman on earth and I'm so glad she chose me. Thank you for being my wife @bsmp2 #mywifeisamazing."
Bristol and Dakota already share 15-month-old daughter Sailor Grace. Bristol shares 8-year-old son Tripp with ex-fiancé Levi Johnston.
The couple announced in March that they are expecting another girl. Bristol is due in May.
