Oy. I don't know what I'm going to do for a carseat this time. DS is still in the only carseat we've ever bought, a Truefit convertible. As far as newborns in convertibles, you just have to be careful to find one that has a reputation for fitting newborns well, the shoulder straps in some convertibles don't come down low enough to be safe. You also have to be sure that the seat is installed at the proper angle, so the baby is really laying back, and their head isn't prone to falling forward. The Truefit was great though, ds was 6 1/2 lbs at birth, and he fit perfectly. The seat came with lots of newborn padding as well, so I didn't have to fuss with rolled up receiving blankets and the like. The problem is, it's a really wide seat, and ds is still rear facing, and the head rest of his seat only fits between the headrests of the front seats of my little car, so he has to be in the middle. But the middle is usually where you want to put the smallest child since it's the safest spot. He has about 4 or 5 lbs to go until we have to turn him around. It's possible he could have a growth spurt and have to forward face by the time baby comes, but it doesn't seem all that likely.
So, I could turn him around early, (not what I want to do) so I could put him on one side of the car and try and find another seat that's skinny enough to fit beside him in the middle. If I can't find a seat that's skinny enough, I guess I'll have to have both seats on the sides, which would still mean turning ds around. Or I could keep ds in the middle and put a skinny seat on one of the sides, which also doesn't seem ideal. I might be able to fit him rearfacing behind one of the front seats, if I put the seat back all the way upright. The problem with that is, I'm really short, and so the head rest of the seat ends up curving forward right into the back of my head (I'm guessing it hits average people on their necks?) so if I can't lean the seat back, I end up driving with my head jutted forward which gives me a massive headache. This problem is probably compounded by the frequency in which I wear my hair in a ponytail.
Add to all that, my car is kind of on it's last legs. We've actually been expecting it to break down for years, and it just keeps ticking. Which is good, because we don't want to spend the money on a new car right now, but what if I go to all this trouble to figure out how to fit another carseat in my car and then it just dies. That would be annoying.
I should really head over to the safety forum and start doing some research, but I'm kind of delaying, hoping that ds will gain some weight and have to be turned around, solving some of the problems.
Oh, and FWIW, I didn't have any trouble transferring ds out of his carseat when he was asleep. Probably just a lucky aspect of his temperament, and the fact that it was summer when he was born, but if he was asleep when we got somewhere, I usually just popped him into my moby wrap and if he woke up in the process, he'd fall asleep again in a few seconds in the wrap. If he fell asleep on the way home, I'd just carry him inside and lay him in his bouncy seat and bounce him for a minute if he was stirring.
