Coupe and Baby Seats

I have 3 kids (5, 4, 3 years old). I used 3 seats 2 years ago but after a few monthes I used only one seat on the front seat, for the smallest kid. The 2 others use the back seat belts, they are not very happy to not see anything, they are seated too low. I know it is a little bit unsecure, but it is only for a few km. It is always possible to do better, but it is probably better to not have any kid nor any car :wink:
