Quoting Rabbit™:" I didn't have one with my first two (on second thought, I think I did with my first. Before I knew better. ... [snip!] ... better. Not 100% though) but with my second daughter they taught me how to position receiving blankets to support her head."This is what our nurse said to do it is also what they told us with I took the car seat safety check certification classes any thing that goes under the baby or straps can be very dangerous
Quoting Blythe.:" i don't understand the difference between the blankets and a different heat support"
Quoting Rabbit™:" The blankets, when properly placed, don't interfere with the car seat harness like the after-market supports do."
Quoting Blythe.:" how do they interfere? "anything that goes under the straps can reposition the straps causing extra slack in a crash also the formed head rests can slip behind the baby's head and cause suffocation. A receiving blanked will unroll in the event of a crash and doesn't pose the same threat as the headrest supports

Quoting Kimberly Majlak:" Honestly i wouldn't mess with it especially if it's attached. If you endup getting into an accident and ... [snip!] ... a padded linner for underneath, but i think the sell them. If it is attached at the very least do not cut it off or anything."
Quoting Blythe.:" somthing like this wouldn't interfere with the straps "This goes behind the baby's head, which voids warranty, also it is formed so it could possible slip down so that the formed area pushes on the back of the head causing suffocation
