I think my daughter will have to be switched sooner than later to a convertible car seat. The problem is right now the infant car seat gets used in three different cars!
I take her to the baby sitter (my aunt) Mon-Fri and leave the car seat since often times they go out and about on little adventures- in fact today they are even going on an hour drive to visit other family. When it comes time to pick her up my husband picks her up. My husband and I each have a base in our cars and the sitter uses a seat belt in hers.
When it comes time for the convertible car seat Ive read a lot about how having two is better and mostly everyone has the same car seats.

Would you buy 3 if you were in this situation? Any recommendations.. these seats don't seem to run cheap and I really wouldn't want to buy something cheap when it comes to my daughters safety anyways!
