Leap 5 (Weeks 23–26): Distance, Separation and the Six-Month Mark
For general reference only, not medical advice. Every baby develops at their own pace. If you are worried about your baby, contact a doctor or other health professional.
Around six months many babies start to protest when a parent walks out of the room, even for a moment. At the same time they are reaching, grabbing, rolling and possibly starting to sit, and many families are also beginning first foods. With so much happening at once, a clingy and unsettled week or two is very common.
This guide covers what parents commonly notice in this window and practical ways to make goodbyes, meals and sleep a little easier.
Typical timing
The fifth window is usually placed at weeks 23 to 26 from the due date, which is close to the six-month mark for a baby born on time. Babies born early usually reach it correspondingly later after birth.
This window often overlaps with first teeth and the start of solids, both of which can affect sleep and mood on their own. If your baby is unsettled, it can be useful to consider all three.
What parents may notice
- Crying or reaching out when a parent moves away, even briefly.
- Wariness with less familiar adults, sometimes even relatives.
- More night waking, or calling out for a parent after waking.
- Strong interest in objects: grabbing, shaking, dropping and mouthing them.
- Rolling in both directions, pivoting on the tummy or sitting with support.
- More babbling, with sounds such as “ba” or “ma”.
What is developing
At around six months babies begin to understand distance. They see that a parent can be close or far away, and that objects can be in, under or behind other things. This is an important step in understanding the world, but it also makes separations more noticeable, which is why goodbyes can suddenly seem harder.
Physical skills are expanding too. Many babies can pass a toy from one hand to the other, bear weight on their legs when held standing, and sit for short periods with support. Their play becomes more deliberate: dropping something to see where it goes is a small experiment, not mischief.
Practical ways to help
- Play peekaboo and hiding games with a cloth over a toy. They help your baby practise the idea that things that disappear come back.
- Say a short, cheerful goodbye and tell your baby you will be back, rather than slipping out unseen.
- Keep talking or singing when you step into the next room so your baby can still hear you.
- Give unfamiliar adults time: let your baby watch from your arms before being handed over.
- Offer safe objects to explore, such as a wooden spoon, a soft ball or stacking cups.
- Give your baby plenty of floor time to roll, pivot and practise sitting, with cushions around for early sitting.
- Keep the bedtime routine steady, and keep night responses calm and brief so nights stay boring.
Sleep, feeding and safety
If you are starting solid food, choose a time when your baby is rested and not too hungry, and keep early meals relaxed. Offer iron-rich foods and soft textures appropriate for age, stay with your baby during every meal, and avoid whole nuts, honey before one year and other foods your doctor advises against. Milk remains the main source of nutrition for now.
Teething can cause drooling, chewing and some irritability. A clean, chilled teething ring can help. Avoid teething necklaces and gels that numb the gums unless your doctor recommends a specific product. Teething does not normally cause a high fever, so a high temperature should be checked rather than blamed on teeth.
When to consult a doctor
Mention it to your doctor if your baby does not reach for objects, shows no affection for familiar caregivers, does not respond to sounds or their name, makes no vowel sounds, seems very stiff or very floppy, or cannot roll in either direction by around six months.
Seek prompt advice for fever, breathing difficulty, repeated vomiting, a rash that does not fade when pressed, or very few wet diapers, whatever the calendar says.
Whatever the calendar says, seek urgent medical help for difficulty breathing, blue or very pale lips or skin, a baby who is unusually floppy or hard to wake, a seizure, a rash that does not fade when pressed, signs of dehydration such as very few wet diapers, repeated forceful vomiting, or a fever of 38°C (100.4°F) or higher in a baby under three months. Trust your instincts: if you feel something is wrong, contact a doctor or emergency service.
