Ms Louwrens said there were lots of children in Whanganui who needed pyjamas, and they would be allowed to take them home when they left hospital. Most of the children admitted to the ward's eight to 12 beds have respiratory problems such as pneumonia, bronchiolitis, bronchitis and asthma.
The children's ward is usually overflowing in winter, she said.
"Pneumonia has been bad for the last few months. It's good to have homes insulated and things like that, to prevent it."
On Monday there were only two babies in the ward, both with bronchiolitis and too ill to be photographed. Three-year-old Ava Wikotu was visiting her mother, who has just had a baby. She and her dad got into the picture instead.
