Maternity Pictures opinions.

We are due May 26 with our baby boy and are taking maternity pictures April 28. We have two outfit changes for our session. One outfit is casual and the other is a strapless white dress with my cowgirl boots and I've seen so many pictures involving a horse and I was wondering if anyone else here has taken their maternity pictures with their horse? Our horse is all white but his face is brown with baby blue eyes and he has been a part of my husbands life for 10 years and we both love him so much and we definitely want to teach our son how to ride too, and this will most likely be the horse we use to teach him! So I was thinking if we put a baby blue blanket on him, he would look perfect in our session. What's your opinion? And please if you did take maternity pictures with your horse, share!
