I got DS a pillow about a month ago. A friend with kids recommended the travel pillow at bed bath and beyond. It is the perfect size for a little one and has a nice fake down filling. They are only 9.99 plus you can use a coupon. They also sell little pillow cases for them you can switch out. She recommended getting a few of them, so if your child wets on the pillow, you can just throw it out since so cheap. DS is still getting used to it, but no issues so far!
We just bought a normal pillow about the time she turned one. She was always sleeping on DS's or ours so getting one for her was a natural step for us. She's has no problems with it.
