I love Brandi's response because she said exactly what I was thinking as I read your request----Are you going to get comfortable? NO YOU'RE NOT! I am in my eighth month of my fourth pregnancy and I just got out of bed feeling like a turtle stuck on my back!
The pillows and leaning/spooning with husband suggestions can be helpful. I could barely walk in the last two months of my third baby and sometimes sat in our hot tub in the middle of the night just to get some relief---keeping in mind the temp of the hot tub was 98 degrees and no higher. I also think that getting a pregnancy massage every now and then will help---so if you have friends or family out there that want to get you something for the baby, have them get some gift certificates for massage.
Best wishes and Congratulations! No one can describe to you the journey to motherhood that you are going down and experiencing it is like no other experience you will ever have in your life.
