Moving my child into a booster seat/cushion
Best not to rush a child into a Group 2/3 booster seat. People often do so for convenience as its very easy to move a booster seat from one car to another where as a Group 1 seat does take a little more time and effort to fit in. Ensure the child is at least 15kg before move them onto it, it’s the legal minimum requirement. Ideally try to keep them in there until about 18kg which is the maximum capacity for a Group 1 seat.
