Dakota Meyer is thankful for his "amazing" wife, Bristol Palin.
The proud hubby gushed over Palin, who is pregnant with their second child together, in a sweet Instagram post on Wednesday.
"I couldn't ask for a better person to be the mother of my children," Meyer captioned a pic of a Bristol getting an ultrasound. "She's the most amazing woman on earth and I'm so glad she chose me. Thank you for being my wife @bsmp2 #mywifeisamazing."
Meyer, 28, and Palin, 26 tied the knot in June, and are expecting another baby girl. The new addition will join the couple's nearly 2-year old daughter, Sailor, and Palin's 8-year-old son, Tripp, from her previous relationship with Levi Johnston.
In March, Palin revealed the sex of her upcoming bundle with an Instagram post reading, "Dakota and Tripp officially outnumbered so excited to let you all know, ITS A GIRL!! "
Palin and Meyer exclusively announced the pregnancy to ET in December. "We are so excited to announce that our family is expanding!" the pair revealed in a statement. "God has blessed us so much; we are thankful for His grace and new beginnings. A springtime baby in the Meyer home and we can't wait!"
