I noticed that your right hip was also replaced. Are you a "hold em on your right hip girl" also? After I read your comment, I realized that not only did I carry a total of 4 babies (2 pregnancies) en utero, but I also literally "carried" them and so many others riding on that right hip---jutting and swaying as I did! A 10+ pound baby---must have felt like a very long pregnancy! I only lasted 7 months with the triplets---they were each 4 1/2 pounds--big babies for only 32 weeks, but your guy was almost the same weight when he came. Now my curiosity is piqued about whether multiples/big babies have a long lasting impact on hips as my nurse friends suggested. Time to do some research!
