DD is 9 mo and currently is in a Maxi Cosi Cabriofix with Isofix base. We were involved in a car accident recently and its made me extra vigilant about safety so I've started researching the next stage car seats. Is it impossible to use an ERF seat in a three door car? I don't think there is much chance of changing the car anytime soon. Are there FF seats that are considered safer if ERF is not suitable? Thanks!
