Why Grief Can Cause a Child to Regress

Regression is a normal grief reaction

When a young child loses someone, the stress of grief can pull them back to earlier, more comforting behaviors. Preschoolers in particular may regress to thumb-sucking or bedwetting after a frightening or sad event; older children may become clingy, want help with self-care they'd outgrown, or revert to baby talk 1Ref 1Substance Abuse and Mental Health Services Administration (SAMHSA) (2023).Tips for Talking With and Helping Children and Youth Cope After a Disaster or Traumatic Event: A Guide for Parents, Caregivers, and Teachers.Preschoolers may regress to thumb-sucking or bedwetting; seek more help if reactions persist beyond 2 to 4 weeks.. This isn't your child being difficult or "going backward" for good — it's a young nervous system seeking safety. It also reflects how children this age understand death: as something confusing and not yet fully permanent, which is unsettling in a way they can't put into words 2Ref 2American Academy of Child and Adolescent Psychiatry (AACAP) (2018).Children and Grief (Facts for Families No. 8).Preschoolers view death as temporary/reversible; children five to nine think more like adults.3Ref 3The Dougy Center: The National Grief Center for Children & Families (2022).Developmental Responses to Grief (Ages 2-18).Ages 2-4 may see death as reversible; ages 4-7 begin to grasp finality..

Why bedwetting specifically can return

Bedwetting is one of the most common stress-related regressions because nighttime, sleep, and being alone in the dark are exactly when a grieving child feels least secure. The body's stress response can also disrupt sleep and bladder control. None of this means your child is doing it on purpose. Shame and punishment tend to make stress-related wetting worse, while reassurance, a calm bedtime routine, and a nightlight tend to help 1Ref 1Substance Abuse and Mental Health Services Administration (SAMHSA) (2023).Tips for Talking With and Helping Children and Youth Cope After a Disaster or Traumatic Event: A Guide for Parents, Caregivers, and Teachers.Preschoolers may regress to thumb-sucking or bedwetting; seek more help if reactions persist beyond 2 to 4 weeks.4Ref 4Substance Abuse and Mental Health Services Administration (SAMHSA) (2025).Tip Sheet: How to Support a Child Through Grief.Honest age-appropriate communication and maintaining routine support a grieving child.. Keep the message simple: this happens sometimes when we're sad, and it will get better.

How to respond at home

• Stay matter-of-fact and warm about accidents — clean up without scolding.
• Protect routines. Familiar mealtimes, bedtimes, and rituals are deeply reassuring and are one of the most protective things you can offer a grieving child 4Ref 4Substance Abuse and Mental Health Services Administration (SAMHSA) (2025).Tip Sheet: How to Support a Child Through Grief.Honest age-appropriate communication and maintaining routine support a grieving child..
• Offer extra closeness for the clinginess rather than pushing independence right now; it usually passes faster when met than when fought.
• Name feelings honestly and in age-appropriate words — let your child know the sad feelings and the wet sheets are connected, and that both are okay 4Ref 4Substance Abuse and Mental Health Services Administration (SAMHSA) (2025).Tip Sheet: How to Support a Child Through Grief.Honest age-appropriate communication and maintaining routine support a grieving child..
• Give it time. Many grief reactions in young children ease within a few weeks 1Ref 1Substance Abuse and Mental Health Services Administration (SAMHSA) (2023).Tips for Talking With and Helping Children and Youth Cope After a Disaster or Traumatic Event: A Guide for Parents, Caregivers, and Teachers.Preschoolers may regress to thumb-sucking or bedwetting; seek more help if reactions persist beyond 2 to 4 weeks..

What's typical versus what to watch

Typical regression is temporary and gradually improves. Pay closer attention if reactions are intense, get worse instead of better, or persist beyond about two to four weeks — that's the window after which experts suggest seeking more help 1Ref 1Substance Abuse and Mental Health Services Administration (SAMHSA) (2023).Tips for Talking With and Helping Children and Youth Cope After a Disaster or Traumatic Event: A Guide for Parents, Caregivers, and Teachers.Preschoolers may regress to thumb-sucking or bedwetting; seek more help if reactions persist beyond 2 to 4 weeks.. Also notice if trauma symptoms — being unable to stop thinking about how the person died, intense fear, or avoidance — seem to be crowding out your child's ability to grieve; that pattern, sometimes called childhood traumatic grief, is different from ordinary grief and worth a conversation with a professional 5Ref 5National Child Traumatic Stress Network (NCTSN) (2020).Childhood Traumatic Grief: Information for Parents and Caregivers.Trauma symptoms can intrude on and impede a child's mourning (childhood traumatic grief)..

When a clinician helps

Your pediatrician is the right first call if regression lingers past a few weeks, worsens, or worries you 1Ref 1Substance Abuse and Mental Health Services Administration (SAMHSA) (2023).Tips for Talking With and Helping Children and Youth Cope After a Disaster or Traumatic Event: A Guide for Parents, Caregivers, and Teachers.Preschoolers may regress to thumb-sucking or bedwetting; seek more help if reactions persist beyond 2 to 4 weeks.. A clinician can rule out medical causes of bedwetting (such as a urinary tract infection or constipation) so you're not assuming it's "just grief," assess whether your child is showing signs of traumatic or prolonged grief, and connect you with evidence-based help — including trauma-focused or grief-focused CBT — when it's indicated 5Ref 5National Child Traumatic Stress Network (NCTSN) (2020).Childhood Traumatic Grief: Information for Parents and Caregivers.Trauma symptoms can intrude on and impede a child's mourning (childhood traumatic grief).6Ref 6Cohen JA, Mannarino AP, Staron VR (2006).A Pilot Study of Modified Cognitive-Behavioral Therapy for Childhood Traumatic Grief (CBT-CTG).Trauma-focused CBT reduces traumatic-grief symptoms in children.7Ref 7Boelen PA, Lenferink LIM, Spuij M (2021).CBT for Prolonged Grief in Children and Adolescents: A Randomized Clinical Trial.Grief-focused CBT reduces prolonged grief and related symptoms in bereaved children.. Pediatric care here is meant to be family-centered and trauma-informed, supporting you and your child together, and can include coordinating with your child's preschool or school 8Ref 8Schonfeld DJ, Demaria T, Nasir A, Kumar S; AAP Committee on Psychosocial Aspects of Child and Family Health and Council on Children and Disasters (2024).Supporting the Grieving Child and Family (Clinical Report).Pediatric support for grieving children should be family-centered and trauma-informed..
