Separation anxiety arrives because something went right

This is less a set of instructions about separation anxiety than an argument, and it is worth saying so at the start.

The mechanism is memory

Very early on, a baby handed to anybody is largely untroubled, because out of sight is genuinely out of mind. Once they can hold you in mind while you are gone, absence becomes something that can be noticed and objected to.

The protest is therefore evidence of a working attachment and a developing memory, arriving alongside other cognitive changes. It typically peaks in the second half of the first year and again around big transitions, with a wide range at both ends.

Sneaking out is the expensive shortcut

Leaving while a child is distracted avoids the immediate scene and teaches that you may vanish without warning at any moment. The predictable result is a child who monitors you more closely and objects earlier next time. A short, cheerful, unambiguous goodbye, said once and then followed through, is worse for thirty seconds and better for weeks.

For most families, coming back and restarting the goodbye is the other common mistake, with the same effect.

Rituals do the reassuring

The same three actions in the same order, coat on the hook, two books, one wave from the window, give a child something they can predict. Prediction is what lowers anxiety; reassurance about how much you love them mostly does not, because that was never the question. A transitional object that smells of home helps some children and does nothing at all for others.

Whatever the ritual contains, keeping it identical matters more than what is in it.

Practise separations that are small

Leaving the room and calling from the hallway, then returning, teaches the pattern at very low cost. Peekaboo is the same lesson in game form, which is roughly why children of this age find it so gripping. Short absences with a familiar adult, built up gradually, work far better than a first separation that is long.

The first day at nursery is a poor place to begin the practice.

The handover is not the day

Most children who scream at the door settle within a few minutes, and staff can usually tell you precisely how long it took. Parents rarely find this out, because they leave without asking and then carry the scene around until pick-up.

Over a term, asking for a message once the child has settled is a small request most settings are glad to accommodate. What you witnessed at the door is not a representative sample of anything.

If something here does not match your family, trust your family.

When to ask for another opinion

Distress that does not settle at all, that is escalating over weeks, or that spreads into sleep, eating and play is worth raising with a health visitor or doctor. Anxiety in an older child that prevents school, sleepovers or ordinary separations is a recognised and treatable pattern rather than a phase to outlast.

A sudden onset in a child who was previously relaxed is worth taking seriously and asking about. Most of the time the answer is that it is developmental, and getting that answer from a professional is worth the appointment.

The takeaway

Say goodbye once, keep the ritual identical, and ask how long it actually lasted.

Most of parenting is repair, not perfection, and repair counts.
