Does having the base installed make it safer?
We're traveling this summer and would rather not schlep base unless we have to.
We found it really useful to have, b/c putting car seat in/out of car (if you want to leave baby in it when you're out and about, e.g., at a restaurant) is a real PITA w/out the base. Really. You can check the base for free on any airline, does not count as a checked bag, and it doesn't have to be in anything - they just put the sticker through one of the holes and send it through. Very easy. Still one more item to schlep, but worth it IMO. Does make it easier to get the car seat angle right, too, which is key w/ babies for their head/neck. I'd take it. Hugs (and I know I owe you a note, coming up for air today as preschool teacher kindly offered to take twinkies all five mornings this week - woot woot! I must REALLY look like "couple #2" - see SB's post above),
