Siblings
We always say that with eating disorders, most of the recovery work happens at home, which is why families are such an essential part of recovery. Medical professionals can get us started and support us along the way, but the bulk of the work is done by the whānau. In fact, we often say that the biggest mental health workforce in New Zealand is whānau. The whole family becomes involved, each in their own way, and every one of them ends up affected by the eating disorder in some way or another.
Siblings, even though they sometimes try not to appear affected, are indeed deeply affected by their sibling's illness. Sometimes they feel guilty, as though perhaps it was something they did that caused this. It is very important to talk to your child and explain that there is nothing they did, nothing their parents did, and nothing the affected individual did themselves to become ill. This is an illness, and there is no blame.
It also helps to remember that siblings often carry their worry quietly. They may pull back to avoid adding to their parents' stress, downplay their own needs, or struggle with a confusing mix of love, fear, frustration, and guilt all at once. Some feel invisible, as though the illness has taken up all the space in the house, while others feel pressure to be the "easy" or "good" child who causes no trouble. None of this means they are coping fine. Make time to check in with siblings regularly, give them honest, age-appropriate information, and set aside a little one-on-one time for them, separate from anything to do with the eating disorder. This reassures them that they matter just as much and that they have not been forgotten.
