DS is 2.8 and currently in a 9 months to 4 years carseat. DD is 10 months and still in her infant carrier. When she has outgrown that, I want her to go in DS's current carseat, but he needs to go somewhere!
As he isn't enormous (about 29lb or so) and also because I don't want him going in a carseat with just an adult belt, I want to get one that has a harness as well. I have a feeling that these seats aren't as safe as the 9 months to 4 years ones - can anyone point me in the direction of anything about this?
I know the alternative is to get another 9 months to 4 years car seat for DD, but then we will end up with a lot of car seats (2 cars so need more car seats).
