The 6-month sleep regression

This guide is general information only and isn't a substitute for medical advice. If you're concerned about your child's health, or they're unwell, please see a doctor.

Six months is a busy month. Solids start, rolling and sitting arrive, and a lot of families notice sleep wobble at exactly the point they thought it was settling down. "Six-month regression" is a parenting term rather than a medical one, but the disruption is real enough, and it usually has identifiable causes.

What's actually going on

Several things land close together. Solids typically start around six months, when most babies show signs of readiness and begin to need iron-rich foods. Rolling and sitting are developing, which gives babies something new to practise in the cot. And around 6 to 9 months is exactly the window in which Raising Children describes gradually reducing settling help as babies move towards self-settling.

Sleep needs are also shifting. Raising Children puts babies at about 14 to 17 hours a day at 2 to 3 months, about 12 to 15 hours from 3 to 6 months, and about 11 to 14 hours by one year, and around now most are moving towards 2 to 3 daytime sleeps, so the day often needs restructuring.

Solids won't fix the nights

It's tempting to read night waking as hunger and to push solids as the solution. Solids are introduced around six months for nutrition and development, especially iron, not as a sleep strategy, and it's worth being honest that starting them earlier is unlikely to buy you a full night. Raising Children advises not introducing solids before four months.

What helps

• Check the day first: the number and timing of naps often needs adjusting at this age.
• Give plenty of daytime floor practice for rolling and sitting, so the cot isn't the rehearsal space.
• If you want to reduce settling help, step it down gradually rather than removing it at once.
• Keep every sleep safe: back to sleep, own safe sleep space, clear cot, and, per Red Nose, stop wrapping as soon as baby shows signs of beginning to roll or reaches three months of age, whichever comes first.

How long

Most families find things settle within a few weeks once the new skills are ordinary and the day has been reshaped. If sleep is still in pieces after several weeks, or nobody is coping, that is a reasonable point to get help.

A few things point to a doctor rather than a settling plan. Raising Children advises seeing your GP if your child snores most nights or over a long period, breathes through their mouth, or gasps, chokes or struggles for breath in their sleep, or is unusually tired or hard to wake during the day. Difficulty breathing, pale, blotchy or blue skin, or being very drowsy or hard to rouse are signs of serious illness that healthdirect says need urgent care. And if your child seems to be in pain, is feeding poorly, or isn't growing or gaining weight as expected, see your GP or child and family health nurse, because no settling method fixes a medical problem.

It's worth saying that the "six-month regression" is not a fixed event, and plenty of babies sail through this month with no disruption at all. If yours does, nothing is wrong and you haven't missed a stage. Naming it is meant to reassure you that a wobble here has obvious causes, not to tell you to expect one.
