We have booster car seats (integrated) in our Chrysler Grand Caravan - front facing, harnessed booster until 50lbs. They are actually working on a 3 in 1, integrated car seat (I've done a ton of research on this subject - both in Canada & US), but it's been years in development as the specifications are very important as it will accommodate various developmental stages.
Basically, my feeling on this matter is that if you are parent, you don't have the luxury of making mistakes such as this. The old argument again, that "I'm not a perfect parent, so I don't feel the need to comment on Britney" is very weak. Everyone's idea of 'perfection' is different, but understanding basic car seat laws or recommendations, is not perfection - that is basic parenting 101. Any 'imperfections' in this area could result in serious injury or death - again, not a chance I'm willing to take.
Lastly, it would seem from most posts on here that people are confused by car seat laws - I've just drafted a letter to the branch of my government that deals with this, as this is a common problem for many parents, but the fact remains, that rear facing is best as it protects immature spines and necks best if in a crash - they rear face in some European countries until the kids are over 3 and guess what? Their infant/child vehicle mortality rates are very low. Infants/toddlers have been rear faced for awhile now and it confuses me as to how parents are more concerned about seeing their kids (buy a baby car seat mirror that attaches to your own), then about them being vegetables should a car accident occur - by the way, not letting your kids eat or drink in the car goes along way in this area as well, as they don't have anything to choke on (this is what I hear most parents are afraid of when kids are rear faced). To me, it makes perfect sense that rear facing protects spines and necks, yet I see many parents (some of you included) who can't seem to figure this out. I hear most parents complain that it's an inconvenience - yikes! How are you going to explain to your child when he/she is paralyzed that you didn't want to be inconvenienced so you didn't properly secure him/her in the appropriate car seat?
This is a debate that will go on forever because: 1) Car seat laws are not specific enough and 2) Parent ignorance, misunderstanding or laziness surrounding these laws. I for one know that I don't have the luxury of making any mistakes with my precious daughter in this area and neither should the rest of you or Britney.
