I have heard the safest seat was a baby capsule (for upto 6mths - I think). Also, there's the convenience of not having to lift bub out of the seat if she's fallen asleep - u just unclip the capsule. I know that there are stores that will hire out the baby capsule - I think for $60 for 6 months which soundfs like a bargain - you can always buy your own sheepskin insert for the hired capsule.
