Hollo, hiring from kidsafe is just fine. You can also hire them from the ambos. There is no "right" time to put it in the car, as long as it is in there before bubs comes home from hossy. If baby arrives early dad can always put it in while you are in hossy, but of course it is easier to have it in before bub arrives. They will help you fit it the first time, after that you should be right to do it yourself.
