Hi I'm looking for a new car seat for my 4 year old. We currently have the maxi cosi Pearl with the isofix. Having looked at options, there are seats that will go all the way to 12 with the car seat belt to strap them in, but also some that will go to 7 or 8 years old. If possible it would be great to hear what you recommend and how your children have found the different kind of car seats as they get older. Obviously safety is the most important factor, but my child gets terrible car sickness so comfort is important too.
