I could really use some advice. My dh has always installed our car seats. Sometime when I moved I misplaced the base to our britax companion. My daughter is 1 month old today and I was trying to use it with out the base but I am just uncomfortable doing it. I never feel like its in right and I am a nervous wreck driving. I had bought the baby a radian to use. Right now I have 1 5 year on in a regent in the back row, 1 2 year old (3 next month) in a boulevard forward facing next to her, in the second row I have another 2 year old (3 next month) in a forward facing boulevard, and then the baby next to her. The regent and boulevard in the back take up almost the whole bench. Since the baby does not like the car I wanted to put the Radian that I had bought for the baby in the back seat to make more room so I could sit back there when dh is driving to calm the baby down. So I was going to then put the baby in the Boulevard rear facing. Okay does that make sense so far? So I have never installed car seats. I get so confused reading these threads and watching the videos. Dh works overtime this weekend and won't be able to switch the seats so I am going to attempt it since we have to go out on Sunday. I keep reading about the latch being loose on the Radians and now I am worried I won't install these right. If anyone has some easy videos to share with me I would really appreciate it. We have a 2006 Honda odyssey.
