DH and I have narrowed down the carseat choice to two diffrent ones. One is an infant carseat and one is a convertible carseat. I like the convertible one because we can use it longer. DH likes the infant one because we won't wake the babe if he/she is asleep getting them in and out of the car. He also said he would feel better having a new carseat as the baby gets older because he is afraid the old one will expire. What do you ladies think? do you have a prefrence between infant and convertible?

Re: Carseat Question
If you can afford to get the infant seat and then a convertible seat later that is probably the best. Infant seats are safer because they are made for small babies as opposed to convertibles that are made for small-larger babies.
Also, your DH makes a good point about the sleeping baby. Think about if you all were going out to eat and your LO fell asleep...would you really want to wake him up? I know I wouldn't!
You should also check with the hospital where you are delivering--mine requires all babies to be in an an infant car seat when taken home.
I prefer both if you are in a position to afford it. And the average expiration date on a carseat is 6 years from the manufacture date. I had to look this up today because DH was concerned that our Britax Marathons were expired. But each car seat is different. Take the ones you are thinking about and do a google search for their expiration date.
And don't forget that if you get the convertible and decide after baby is born that you really want an infant seat you can put the converitible aside and buy an infant seat.
But before you do that check with your hospital. I have also heard that certain ones will not let you leave without an infant seat.
