This guide is general education that summarizes published research and guidance from groups like the American Academy of Pediatrics, the CDC, and the WHO. It isn’t medical advice, and every child develops on their own timeline. Your pediatrician knows your child; if something feels wrong, call them. In an emergency, call 911.

Some babies grin at the mail carrier. Some study a grandparent for a full minute first. Today is about the second kind, and why that's a temperament, not a problem.

## Heart

Between 4 and 7 months, many babies turn from fairly passive to eager and assertive, and their temperament becomes clearer ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Emotional-and-Social-Development-4-7-Months.aspx)). Some are easygoing; others are intense or slow to warm up. A quiet, sensitive baby needs extra time and people who approach slowly, and may need your attention more than they show ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Emotional-and-Social-Development-4-7-Months.aspx)). Stranger anxiety usually arrives at 7 to 12 months ([AAP](https://www.healthychildren.org/English/family-life/work-and-child-care/Pages/making-baby-drop-off-at-child-care-easier.aspx)), but some babies are wary earlier, and this week you may be meeting one.

## Head

A study of 1,285 twins tracked fear of strangers from 6 to 36 months. On average, it rose between 6 and 12 months. About 1 in 4 babies were already quite fearful at 6 months, and half of those became less fearful by age 3 ([Brooker et al., 2013](https://pubmed.ncbi.nlm.nih.gov/24118713/)). So a wary baby now is common, and often temporary. It is also not a verdict on the visitor, or on you: a rise in wariness over these months was the average course in that study, not a sign something went wrong ([Brooker et al., 2013](https://pubmed.ncbi.nlm.nih.gov/24118713/)), so the people you love should keep showing up, at your baby's pace.

## Body

The technique is patience with a script. Hold your baby while visitors talk to you first, then let your baby decide when to look, smile, or reach ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Emotional-and-Social-Development-4-7-Months.aspx)). The guide's version: "This is Grandpa. We're going to watch him for a minute." Grandpa talks to you, not the baby, until the baby leans in. Cuddling, talking, and distraction can calm an intense baby if the visit tips over ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Emotional-and-Social-Development-4-7-Months.aspx)); the slow-to-warm one just needs the minute.

### The warm-up minute

- **Time:** 1 minute per visitor
- **From the guide:** [Let new people warm up](https://chorevia.com/learn/5-months#let-new-people-warm-up)

1. Hold your baby facing the room and say the line: "This is Grandpa. We're going to watch him for a minute."
2. The visitor talks to you, not the baby, for a full minute, sitting, without reaching ([AAP](https://www.healthychildren.org/English/ages-stages/baby/Pages/Emotional-and-Social-Development-4-7-Months.aspx)).
3. Watch for the lean, the smile, or the reach. When it comes, let the visitor offer a finger, and only then a hold.
4. If your baby turns into your shoulder instead, go back to step 2. No "go to Grandpa," and no passing them over to see what happens.

**Make it work:** Say the visitor's name every time, in the people book and at the door; naming the people your baby meets is an easy habit, though its long-term effects haven't been tested ([Scott & Monesson, 2009](https://pubmed.ncbi.nlm.nih.gov/19422630/)).

## Watch for

- **Normal:** a long, serious stare at a new face, then a turn into your neck. **Talk with your pediatrician** if your baby doesn't laugh or seem to know familiar people, skills most babies have by 6 months ([CDC](https://www.cdc.gov/act-early/milestones/6-months.html)); don't wait and see ([CDC](https://www.cdc.gov/act-early/families/concerned.html)).
- **Normal:** crying when handed to a visitor and stopping the moment they're back with you. **Go to the ER now** if your baby screams and can't be consoled, or cries when you touch or move them ([AAP](https://www.healthychildren.org/English/tips-tools/symptom-checker/Pages/symptomviewer.aspx?symptom=Crying+Child+-+3+Months+and+Older)).
- **Normal:** a baby who is wary with everyone this week and fine next week; shyness at 6 months often fades ([Brooker et al., 2013](https://pubmed.ncbi.nlm.nih.gov/24118713/)). **Call your pediatrician right away** if your baby has a fever higher than 104°F (40°C), or looks or acts very sick ([AAP](https://www.healthychildren.org/English/tips-tools/symptom-checker/Pages/symptomviewer.aspx?symptom=Fever)).
- **Normal:** knowing this baby better than anyone alive. **Call anyway** if your baby just doesn't seem right to you. Trust your instincts; twenty-four weeks have made them sharp ([Lurie Children's](https://www.luriechildrens.org/en/blog/when-to-call-the-pediatrician-for-your-newborn/)).

## For you

Your own temperament with visitors. Some mothers want a full house at twenty-four weeks; some want the door shut and one person at a time, and the second is a preference, not a symptom. The line between wanting fewer visitors and wanting none of anything is the one to watch: low mood, anxiety, or emptiness that is severe or lasts more than 2 weeks may be postpartum depression, and it responds to treatment ([NIMH](https://www.nimh.nih.gov/health/publications/perinatal-depression)). If sadness has lasted more than two weeks, go to the doctor rather than waiting for a visit ([OWH](https://womenshealth.gov/pregnancy/childbirth-and-beyond/recovering-birth)).

If you're the partner: host. Take the coats, run the warm-up minute, and let her sit with the baby while the room comes to them.
