No flames here!

but please
do research why rear facing at this age is so important. Recent research shows that children under the age of two that are f/fing are 5x more likely to suffer serious injury (or worse) in a crash than kids who are rear facing. The AAP actually recommends rear facing to the limit of the convertible car seat (30, 33, or 35lbs in the US, or until there is an inch or less of shell above the head).
A couple of tips that may help your LO be a little happier r/fing...
1) if your LO is riding in a rear facing convertible, and has good head control, the seat can be as upright as he is comfy with. Usually 30-35 degrees.
Sometimes babies like to be MORE reclined so if the seat is upright already you might try putting it at a
greater recline (no more than 45 degrees though) to see if that helps at all. This site
HERE shows how to guestimate a rear facing angle. Also if you click on the words
Rear Facing here is a whole section on why rear facing is safest. It has absolutely
nothing to do with weight, or whether the feet are touching the back of the seat, or how much head control the baby has, it has
everything to do with age and body development.
2) you mentioned that your LO just wants to see you. I suggest getting this mirror here (
Baby in Sight Mega Mirror) for your vehicle. This one is extra large, and was recommended by another parent on a car safety tips board who had similar issues w/their infant, and the mirror resolved 99% of the problem.
3) Have you tried Music in the car? you might try singing a familiar song or playing a "favorite" CD. Calming childrens music, or whatever works!
4)
soft books and/or toys for him to look at.
5) whenever possible, have someone ride in the back seat w/him.
6) Maybe try a different seating position. If he's in the middle move him outboard. If he's on the side move him to the middle or other side (provided you can get a good install of course).
7) make sure the sun isn't in his eyes. There is film
like this you can buy that sticks to the inside of the windows that is safe to use. someone on another board also suggested
this car seat canopy made by combi.
8) snacks like Gerber puffs that he only gets in the car (I mention those because while not the healthiest, they melt in the mouth).
9) make sure the straps are adjusted properly - for rearfacing they should be At or below the shoulders. If the crotch strap is adjustable make sure it's in the most comfortable position. The harness should be as snug as a hug, but not so tight it's pushing down on the child (just should not be able to pinch any at the shoulder blade). Make sure the harness straps are not rubbing on the neck. Also since it's winter - don't dress the child in fluffy jackets or outerwear. Those can compress in a crash and cause the harness to be too loose, but also they might cause the child to be too warm once the car warms up. Dress in thin layers, and micro fleece works really well in car seats. A blanket over the top keeps the child warm when needed and is easy to remove. fluffy clothing can restrict movement too.
10) Sometimes at this stage LO's feet will touch the back of the vehicle seat which is NOT a safety concern - but it may make them a little annoyed if they can't figure out where to put their feet. Maybe gently show him how to bend his legs or different ways he could put his feet straight on the back of the vehicle seat or "froggy" style. See
this photo album of older kids r/fing and you can get some ideas there.
10) If your vehicle has adjustable seatbacks in the back seat (ie some SUV's and mini van back seats can be reclined somewhat) you might try reclining the vehicle seatback a notch or two to give the child more leg room (make sure you can't move the car seat side to side more than an inch when you do this).
11)lastly you may want to invest in some good earplugs. J/K!!
I hope some of these tips help!
