Do I need to have an authorised person do the installation and get a certificate?
I've been hearing this a few times from family and friends that car insurance can deny your claim if you don't have certificate to prove the child seat was appropriately fitted. I couldn't find anything about it online and I'm with Budget Direct and Woolworths for my two cars.
It seems pretty ridiculous to need a certificate as I may have to constantly take the child seat out to make space, move between cars, pick up Ikea furniture from marketplace, etc.
Also, brownie points if you can chuck in your best first-time dad tip.
Call your insurance? read their PDS? start there.
