Kacbu lists 4 Tablets that stand out for Kids: Amazon, Lenovo, OnePlus. This is not a ranking; each product is here because its editorial assessment found it strong for this use.
For a child what decides is toughness, parental-control software and a price you would not grieve over a drop. The fastest device is not needed; a body that takes a case and a system that can limit content matter more. Look at where the maker states which devices offer a kids mode or parental controls.
Each card carries what sets the product apart. Open the product page for its strengths, weaknesses and alternatives.
