double carer; person caring for both a child and an elderly relative
A social welfare term for someone simultaneously raising a child and caring for an aging parent or other older relative. Often discussed in the context of the 'double care' burden.
Double carers are often pressed by both child-rearing and nursing care.
As a double carer, she is very busy every day.
From English 'double' + 'carer'. A relatively recent loanword used in Japanese social policy and caregiving contexts.
