This is a car seat question that I hope someone might be able to answer.
When we move to Australia from Europe next month, four children are going to need to travel in a grandparent's 5-seater car for school drop-off and pick-ups and some other journeys. The oldest child (mine!), a tallish 7-8 year old, will therefore have to travel in the front seat.
Obviously, no child travelling in the front is ideal, but the grandparent is not going to buy a new car, so please no 7-seater suggestions!
Legally, my child can of course travel in the front, but I want her to have a booster seat until she is 145cm tall, as the safety guidelines suggest. The only seat I can find in Australia for her height and age group, 8-10, is the excellent-looking Safe n Sound encore 10, but in Australia this seat is illegal to use without the tether (there are plenty of boosters of similar dimensions where we currently live that can be used without tethers, but this is the law in Australia).
My child's shoulders are too high for the usual 4-8 year boosters, so the tetherless Safe n Sound Tourer or InfaSecure folding booster are not options for us.
Does anyone have experience of adding an anchor point to a front seat? I understand from Britax that the Booster seat tethers are not safety features, but are to prevent the seat from being a missile in a car if unoccupied in a crash. However, I do not want to ask the grandparent to break the law by having my child in the front in the Safe n Sound encore 10 without the tether attachment.
Has anyone added an anchor point in this position, or does anyone have other car seat suggestions?
