Just got MA but DS head needs support - HELP

[oneontheway]

I just installed the MA in my car, DS seems comfy until he falls asleep and then he has no head support. I tried to put in one of those U shaped support cushions but it isn't tall enough so then his head is smushed downward. Has anyone here found a good solution to give DC some support?

Thank you!

Is his head falling sideways (perfectly ok, not uncomfortable or dangerous, just looks bad to us stiff old grownups), or forward (chin on chest...bad...could interfere with his airway)? How's the recline? If it's not a full 45 degrees (the shoulderbelt lockoff on the side a perfect diagonal), you can tug the tether to get it down to that point (don't make it MORE flat than a perfect diagonal, though).

His head usually slumps to the side. So this is perfectly safe and comfy for him? It looks terrible but I guess as a newborn they are pretty agile. Thanks for the help!
