Hi, we have a saab estate 95 and expecting a third baby soon. We currently have a 2 year old and 4 year old..the oldest is in a full back booster seat and the 2 year old normal car seat. With the baby car seat in the back as well they will all have to shift along so is it safe to have a car seat strapped into the middle seat. It does have a seat belt but heard a rumour that it is not counted as a real seat but as an occasional seat. It will be a squeeze but is it safe does anyone know. Saab garage did not know! Or are we destined for mpv territory?!
