Every winter, Sollitt makes a trip to a Whanganui store that sells children's pyjamas, purchases a pair and then drops them off to the children's ward.
Every year he changes it up on who he is going to buy for and this year he chose a girl's pair of pyjamas for a 10 to 11-year-old.
He said the nurses were very appreciative when he handed them the bag of clothes.
Sollitt worked with children for many years when he managed the Whanganui East Pool.
He said children came into his office all the time and all wanted to talk.
"A lot of those kids, they didn't have much."
Because of this, he is also passionate about teenagers' mental health and wants to help young people get through difficult times.
"If I can cheer something on that other people can donate to as well, and if they don't want to go and take them up [to the hospital], then they can give me a ring and I'll collect them and take them up there for them."
He said anyone who wishes to donate a pair of pyjamas to the children's ward can contact him on 027 847 2769.
