@amaperalta03, I'm not going against what you are saying at all because we rear face too but I went to the EMS department and apparently in Wisconsin they recommend you rear face but it's not enforced. So not all places will require you to rear face which sucks.
You need to rear face him hun. He's still small reason why his head is falling over. If you have him rear faces and at the corrected level he's head won't fall over
