Do toddlers really need them? I've seen some with a kind of raised bit on three sides but are they for younger kids? DD will sleep on her front, side and back on any given night, and from my own experience with a bad back I'm not sure pillows are that good for spine alignment.
Any advice/expert orthopaedic knowledge out there? Recommendations?
I'm not sure what you mean by the pillow with the raised sides as have never seen one, but DS1 (3yo) has a pillow on his bed that he NEVER uses; DS2 (14mo) who suffers with a lot of colds and is a terrible sleeper, has a pillow and it seems to have helped quite a bit.
