Hi There, Is there a minimum height restriction for this?

Hi Kathryn, the Diono Solana 2 Half Booster doesn’t have a minimum height restriction. However it does have a minimum weight restriction of: 18kg. If you are worries though, feel free to go into your local Baby On The Move and get it fitted. Here is a list of our Store Locations here: https://www.babyonthemove.co.nz/store-locations/. Hope that helps
