Question transition from baby car seat to booster

[Unregistered]

Hi
I have 3 year old twins and a nearly 5 year old. I have no third row in my car so i have three clek foomf seats across which works quite well
The eldest is going to transition to a booster seat so we bought a graco turbobooster lx and my question is, is it a good idea to have two larger seats and then a booster next to them, seems to me in a side impact accident the heavier seats could crush the booster seat? Is it better to wait and transition them all together to booster seats and if so when would be the optimal time to do this

It is fine to have a booster with 2 harnesses. However, I have found that's really much harder to buckle, so my preference in your situation would be to keep the 5 year old in the harness until it's outgrown, for convenience. It's entirely up to you though. (The seat will be outgrown when the child's shoulders are over the top harness setting, or the weight limit is exceeded.)
