The same safety precautions developed for children under the age of three are important because they will put anything in their mouth and when you least expect it. Spontaneous use of their hands is accompanied by putting everything in their mouth, along with the risk of choking.
Advise friends, family members and other carers that they are safer with objects that are about 1 inch (2½ cm) in diameter. Equivalent objects have equivalent, single action verbs such as reach, grasp, release, toss, drop, fold, sort, place, handover, wave and pinch.
