Great for 4 kids!
We've been getting Diono car seats since our daughter was born. It was a big deal to go against the whole carry and click mentally, but I felt the Diono was a safer option. Having twins in 2020 with both older kids still using their Dionos car seats meant we had to change it up a little, but we just bought a new car, the big kids have graduated to new booster seats and the twins have a Diono in each vehicle. They're great!
