We also have a developmental care team to help out our little ones. We recently starting using several positioning products, instead of millions of linens to acheive the same effect. The staff has been pretty receptive to this change and the babies seem comfortable and happy. As with anything, it does take a little while for people to get used to the change but now it's just the norm. We also work closely with OT/PT to help identify any issues that they are seeing regularly so that we can help educate the staff on how to avoid these problems and treat them when they arise. Below is a link to the company that makes the positioning products that we use. I hope this helps!
