My 11 week old DD is a great back sleeper, but loves to keep her head turned to the right. When she is sleeping soundly, I turn it to the left (otherwise she fights it) and she'll stay there awhile, but always turns back to the right. Sometimes, I have her sleep on my chest which keeps her off the back of her head, however she is still getting quite the flat spot, with a point at the top, I might add! The Ped said it would straighten out on it's own when she is more mobile, but I still don't like it. Just wondered if anyone has used this product and what you thought of it.
