R100 – could it work for newborn?

Hi Sarah, Thanks for your enquiry, The Diono Radian R100 is suitable from 2.3 kgs rear facing. however it doesnt have as many safety features as the RXT. we would reccomend using the product comparrison on our website to view the difference between the two models. I hope this helps. https://www.babyonthemove.co.nz/index.php?route=product/compare
