Our grandchildren are aged 7 and 6 and now that the car seat backs need to be raised there's no room for a middle passenger. Our daughter is a single parent and we frequently travel in one car for day trips and holidays. Ideally we would like to be able to fit in 2 car seats in the back seat and still be able to fit a passenger between them. Fortunately our daughter is very slim and the children are on the smaller side , but it may still be an issue. The problem is around the head room for the middle passenger.
Can anyone recommend a car seat that is narrow enough to achieve what we want? The car is a VW Tiguan and the current car seats are Kiddy Guardianfix. My daughter is keeping the car seats she has for her car, but looks like we need something slimmer for our cars. Thanks.
