Your baby at 35 weeks: stranger radar

Medically-informed · Sources: CDC · Updated June 2026

Stranger wariness commonly sharpens: the same grandma who got smiles last month may get suspicion first. It's memory, not manners.

What’s happening

Why the cold shoulder

Baby now firmly knows who's who — and treats unknown faces as pending review. Commonly seen from 8 months and often lasting well into the second year in waves.

The slow-warm protocol

Visitors succeed by ignoring baby at first: talk to you, stay at distance, let baby approach. Handing baby over cold commonly backfires.

Home base behavior

Expect check-back-and-explore loops: crawl away, look back, return, repeat. You're the charging dock.

What to do

  • Brief visitors on the slow-warm rule before they arrive
  • Keep hellos and handoffs unhurried — baby sets the pace
  • Practice short separations at home with cheerful returns

When to check in

Total absence of preference for familiar people is worth mentioning at a visit.
