PARENTS across Australia have felt pain in their hearts over the case of missing child William Tyrell.
William's disappearance has remained a mystery since he vanished from his grandmother's home at Kendall last year.
Next month, about 60 simultaneous walks will head off around the country to mark a year since the day William disappeared.
One of the National Walk 4 William events is being held at Liverpool by the staff of SLOOSH Kids Care in Miller.
At the weekend, the centre held a Superman mask-making fun day, that also encouraged discussion about stranger danger.
SLOOSH Kids Care owner Ruth Brissett-Costa said the day was a chance for parents, children and staff to be pro-active and engage in a fun interactive activity.
"The reason why most children will go away with someone is because most of them are living in safe, caring, nurturing homes, so they presume that adults are safe and caring and looking out for them," she said.
"It was also an opportunity for other walk organisers to meet and greet and discuss the coming walk.
"And to make sure we're all standing true to the Walk 4 William vision — to spread awareness and dig deep into our hearts, not our pockets."
The Liverpool Walk 4 William event will be held at 10.30am on Saturday, September 12.
Participants will walk from the Michael Wenden Aquatic Leisure Centre at 62 Cabramatta Avenue at Miller and finish at Powell Park on Hoxton Park Road at Cartwright to raise awareness of the toddler's disappearance and stranger danger.
