How parental illness affects the household
Household dysfunction means disruption to a child's safety, care or relationships. Describe concretely what is happening, rather than treating it as a diagnosis of the family.
A parent's symptoms can interact with poverty, substance use, conflict and disrupted services. But mental illness does not necessarily impair parenting.
Disruption | Possible effect on the child |
|---|---|
Unpredictable routines | Inconsistent sleep, meals, school attendance or supervision |
Conflict and domestic abuse | Fear, hypervigilance (being constantly on guard) and limits on safe relationships |
Repeated separations | Changes of carer, uncertainty and interrupted attachments |
Secrecy or stigma | Isolation and difficulty asking for help |
Too much caring responsibility | Less time for education, friends, rest and play |
Parentification is when a child takes on adult responsibilities that are not appropriate for their stage of development, including managing a parent's emotional needs.
Cumulative adversity (several adversities adding up) can make a child more vulnerable. But counting exposures does not tell you an individual child's prognosis.
Assessing how the child is functioning
Cover safety, daily care, education, friendships, emotional wellbeing and the child's own understanding of what has happened.
Informants may describe the child differently. This may reflect a real difference between home and school, rather than one person being unreliable.
Look for strengths: stable relationships, predictable routines and the child's interests. These can support recovery even while the parent is still unwell.
Coordinating support
Practical help. When food, housing, transport, childcare or money problems affect the child's care, address them alongside the parent's mental health treatment.
Clear roles. Adult and child services should agree who will review parenting and the child's needs. Neither should assume the other service is doing it.
Young carer's assessment. This looks at how caring affects the child and what support they need, under the relevant local framework.
Safeguarding. Act promptly when you suspect harm. Support can still be offered before a child-protection threshold is reached.
