Signs your child is struggling with the separation: how to recognise them
Children of divorced parents go through an adjustment process that can last months or even years. It is completely normal for them to show sadness, confusion or anger during the first few weeks. However, there is an important difference between a temporary adjustment reaction and persistent signs that something is genuinely wrong.
All children are affected in some way by their parents' separation. But while most adapt reasonably well within one to two years, a significant proportion develop emotional, behavioural or academic problems that require attention. The key is knowing how to distinguish between what is expected and what is concerning.
As a parent, you know your child better than anyone. Trust your instincts, but also learn to recognise the warning signs that child psychology professionals have identified as indicators of a difficult adjustment process.
According to the Asociación Española de Pediatría, between 20% and 25% of children of divorced parents show significant adjustment problems, compared with 10% of children in intact families. Early detection is essential to intervene in time.
The 7 warning signs you should not ignore
1. Sudden drops in academic performance
A sharp fall in grades is one of the most visible signs that a child is suffering emotionally. A student who consistently achieved good marks and suddenly starts failing several subjects has not simply become lazy overnight. Their mind is busy processing emotions they do not know how to manage, leaving little energy for concentrating on fractions or grammar.
Pay attention not only to grades but also to teachers' comments. "He seems distracted in class," "She no longer participates," "He is not handing in his homework" — these are clear signals that something is worrying them. Talk to their teachers and ask to be kept informed of any changes they observe. It is important that both parents stay up to date with the child's progress at school, regardless of which home the child is in that week.
2. Regression in behaviour
Regressions are especially common in younger children, although they can also appear in pre-adolescents. A six-year-old who starts wetting the bed again after months of being dry, a four-year-old who begins sucking their thumb again, or an eight-year-old who suddenly refuses to sleep alone — all of these are signs that the child is seeking the security of an earlier stage that felt more stable.
These regressions are the child's way of communicating distress when they lack the words to express it. Do not scold or embarrass them for it. Respond with patience and warmth, reinforcing their sense of security. In most cases, regressions subside once the child begins to feel more secure within the new family structure.
3. Sleep or eating problems
Emotional stress frequently manifests through sleep and eating — the two biological areas most sensitive to changes in a child's environment. Recurring nightmares, difficulty falling asleep, waking during the night, loss of appetite, or conversely eating too much as a source of comfort, are all signs that should be taken seriously.
Observe whether these changes coincide with transition days between homes or with specific events related to the separation. Sometimes a child sleeps perfectly in one home but has nightmares in the other, which may indicate that something in that environment is generating anxiety. Maintaining consistent sleep and mealtimes routines in both homes is essential, and sharing this information between parents helps identify patterns.
4. Unusual aggression or irritability
A child who was previously calm and who suddenly starts hitting classmates, speaking rudely to adults, or having disproportionate tantrums is expressing pain they do not know how to channel. Anger is, in many cases, the most accessible emotion for children. It is easier to be angry than to be sad, frightened or confused.
In adolescents, this irritability may manifest as door-slamming, curt responses, constant defiance of rules, or even risk-taking behaviour. It is essential not to respond to aggression with more aggression. Behind that behaviour is a child who is suffering and who needs to feel that their parents are a safe place — even when they are not behaving well themselves.
Set firm but empathetic boundaries: "I understand you're angry, but you cannot hit. Let's find another way to express how you feel."
5. Social withdrawal
If your child no longer wants to visit friends, refuses to take part in activities they previously enjoyed, or spends more and more time alone in their room, this is a cause for concern. Social withdrawal in children and adolescents is a recognised indicator of emotional distress and, in more serious cases, may be associated with depressive symptoms.
Some children withdraw because they feel ashamed of their family situation. Others do so because they lack the emotional energy to maintain social relationships. And some simply need time and space to process what is happening. The key factor is duration: a few weeks of greater withdrawal may be normal, but if the isolation persists for more than two months, it is time to act.
6. Physical symptoms with no medical cause
Frequent headaches, stomach aches, nausea before school, or persistent complaints of feeling unwell that the paediatrician cannot explain medically are what psychologists call somatisation: the body expressing what the mind cannot put into words.
This phenomenon is especially common in children between the ages of 5 and 10, who are already aware enough to suffer but do not yet have the emotional vocabulary to describe what they feel. A child who says their stomach hurts every Monday morning may be expressing anxiety about returning to school after a weekend with the other parent, or fear that something bad will happen while they are away.
Do not dismiss these complaints with "there's nothing wrong with you." But do not over-reinforce them either. Validate their discomfort and help them name what they are feeling: "Sometimes, when we're worried, our tummy lets us know. Is there something that's bothering you?"
7. Attempts to reunite the parents
Fantasising about parents getting back together is universal among children of separated parents. But when that fantasy becomes an active campaign — with phrases like "If you're good, Dad will come back," strategies to get the parents to spend time together, or deliberate sabotage of a parent's new relationship — it is a sign that the child has not accepted the reality of the separation.
These attempts reveal that the child is still stuck in the denial phase and is not progressing through their adjustment process. It is important to be compassionate but clear: "I understand you'd like us to live together, and it's normal to feel that way. But Mum and Dad are not going to get back together. What will always be true is that we both love you very much."
What you can do if you notice these signs
Identifying the problem is the first step. Taking action is the second. Here are the most effective strategies according to child psychology professionals.
- Talk to your child: Find a calm, unhurried moment. Do not interrogate them; simply open the door: "I've noticed you've been quieter lately. I want you to know you can tell me anything." Sometimes, just knowing that the adult is available is enough for the child to start opening up.
- Reinforce stability across both homes: Children need to feel they have one world, even if it is split across two households. Keeping similar schedules, rules and routines in both homes reduces anxiety around transitions. A tool like Niddo makes it easy to coordinate calendars, share notes on the child's emotional wellbeing, and ensure both parents are aligned — without the need for lengthy conversations that often end in arguments.
- Coordinate with the other parent: Even if the relationship is difficult, your child's wellbeing requires both parents to be informed and to act consistently. If your child is having nightmares at your home, the other parent needs to know. If their grades have dropped, both of you should be aware. Good communication between parents is the best investment you can make in your child's emotional health.
- Keep the activities that bring them joy: Do not let the separation take away the things that make your child happy. If they love football, make sure they can keep attending training regardless of which parent they are with. If they have a group of friends in the neighbourhood, help them stay connected. Continuity in their activities is a well-established protective factor.
- Take care of your own emotional state: Children absorb their parents' stress like sponges. If you are overwhelmed, your child will sense it. Learning to manage your own emotions as a separated parent and prioritising self-care is essential — because looking after yourself is looking after your child.
When to seek professional help
Not every warning sign requires immediate therapy. Many are normal reactions that subside with time, patience and adequate parental support. However, there are situations in which professional intervention is necessary.
Seek help from a child psychologist if:
- The signs persist for more than three months without improvement.
- Academic performance continues to decline despite your efforts.
- The child expresses a desire to hurt themselves or talks about death repeatedly.
- Regressions are severe and interfere with daily life.
- Social withdrawal is complete and the child refuses to leave the house.
- Risk-taking behaviours appear in adolescents: substance use, self-harm, or early sexual behaviour.
Do not wait for the situation to become serious before asking for help. Early intervention, when problems are still manageable, is far more effective than acting once the child is already in crisis. Your paediatrician can refer you to a professional who specialises in children and families.
If you need guidance on how to explain the situation to your children, remember that adapting the message to their age is key to helping them process it in a healthy way.
Your attention makes the difference
Separation does not have to leave a lasting mark on your children. The research is clear: what determines the long-term impact is not the divorce itself, but how the parents manage it. Our complete co-parenting guide offers a practical framework for organising shared parenting in a way that minimises conflict and maximises stability. A low-conflict environment with stable routines, open communication, and the reassurance that both parents remain present allows the vast majority of children to adapt and move forward normally.
Being alert to warning signs is not alarmist — it is being a good parent. And responding to them, whether through a conversation, a change in routines or the help of a professional, gives your child the most important message of all: I am here and you matter to me.
Organise your co-parenting so your children only have to worry about being children. Download Niddo and make sure that coordination across two homes runs smoothly, with a shared custody calendar that keeps both of you informed and aligned.
