## TLDR

- Wariness of new people often starts around 6-9 months and peaks at 8-12 months. It's a sign of healthy development.
- Let your baby watch from your arms, ask visitors to go slow, and don't force hugs or passing around.
- Reassure hurt relatives it's a phase. Mention it if by 9 months your baby doesn't seem to recognize familiar people.

## What's normal

- Around 6 to 9 months, many babies who once smiled at everyone start to stare, cling, turn away or
  cry when an unfamiliar person comes close. The CDC lists shyness or fear with strangers as a
  typical 9-month milestone.
- It often peaks between about 8 and 12 months and can continue into the second year, then
  fades gradually. Some babies barely show it; others show it strongly.
- It's a sign of healthy development. Your baby now tells familiar from unfamiliar faces and has a
  clear sense of who their trusted people are.
- It can include relatives and friends the baby doesn't see often, including a grandparent
  visiting from far away or a parent's partner who is new to the family. It isn't a judgment of
  that person.
- Temperament matters: cautious, slow-to-warm babies may react more and for longer.

## How to help

- **Let your baby watch from your arms first.** A few minutes of sitting close, while the new
  person talks to you, lets the baby study them safely.
- **Ask visitors to go slow.** Say hello to the parent first, smile, keep a little distance, and
  let the baby make the first move. Offering a toy works better than reaching for the baby.
- **Don't force hugs, kisses or being passed around.** Taking turns holding can wait until the baby
  seems at ease.
- **Stay warm and relaxed.** Babies check your face to decide if someone is safe. A friendly tone
  with the visitor helps.
- **Name it calmly:** "That's Auntie. She's a new face. I'm right here."
- **Practice in small doses.** Short visits, playgroups, library story time and video calls
  with relatives help faces become familiar.
- **Bring comfort items** to big gatherings and plan a quiet room or a short walk if it gets to be
  too much.

## Childcare and new caregivers

- Introduce a new sitter, nanny or childcare teacher with you there first, for a few visits if
  possible.
- Show the caregiver your baby's favorite songs and soothing tricks. A familiar routine eases
  the handoff (see the caregiver handoff sheet guide).
- Stranger anxiety often appears alongside separation anxiety at drop-off. See the separation
  anxiety and childcare guide.

## For relatives who feel hurt

- Explain that it's a phase of normal development, not about them.
- Grandparents and extended family can help by visiting often, video chatting, using the same
  songs and games, and letting the baby warm up at their own pace.

## Body autonomy starts early

- Respecting a baby's wariness, without pushing them into anyone's arms, is an early step in
  teaching that their body and feelings matter (see the body safety and consent guide).

## When to check in

- Mention it at the next checkup if, by 9 months, your baby doesn't seem to recognize familiar
  people or show different reactions to them, or doesn't look when you call their name.
- Bring it up if fear of new people is so intense and lasting into the toddler and preschool
  years that it keeps your child from everyday activities.
