DD1 is 105cm tall and 15-16kg
her shoulders sit an inch or two above the shoulder straps of her current baby seat (safe and sound cheap one thats suitable from birth to possibly 18kg).
Online research (american academy of paediatric something) suggests that lap and sash belt with a booster with seat belt guide is safer than the added harnesses that can be added to some of the seat belts. Do you agree?
apparently there are no seats on the market with built in harness for over 18kg. is this true?
which booster with seat belt guide that is narrow and reasonably priced do you recommend?
Thanks so much for answering these questions!
