What I did to prevent a last head was to keep my kids on their sides. I would alternate sides. So after every feeding or diaper change I’d flip them. When your baby is awake keep her off her back as much as you can (tummy time, baby wearing, or just carry her) I wouldn’t put pillows near her but a rolled up receiving blanket to keep her positioned is ok. That’s what I used to do.

My son did something similar. It ended up being torticollis. He had to go to physical therapy and get a helmet. If you’re concerned, definitely talk to your doctor. The sooner, the better!
