The red and white "Age Warning" logo that consists of an unhappy child's face alongside the numbers "0-3", first appeared on toys in 1995 and means that the toy is unsuitable for children that are younger than three years old. Sometimes, you may find the logo referred to as the "grumpy baby" symbol!

and you must include the harm and the hazard (ie small ball: choke risk, long cord: strangulation hazard) or you may use the 0-3 symbol (the grumpy baby symbol!), The symbol must have a white background, red strike, and needs to be 10mm tall. It must only apply to the 0-3 age to avoid any confusion.
