Our capsule only went to 9kgs. The convertable backwards/forwards carseat said forward facing from 8 which is when I put her in it facing forwards because she was too long for her small capsule even though within weight range and neither of our cars would fit the car seat facing backwards without pushing dangerously against the front seats. The weight limit is much more important than age - don't turn till reaches the limit - don't turn if you don't have to - we had to.
