When Do Babies Start Smiling?

Few moments melt a parent’s heart like seeing that first real smile. While newborn smiles may happen in sleep or as reflexes, true social smiles — the ones full of joy and connection — usually appear between 6 and 8 weeks of age.

Every baby is unique, but smiling is one of the earliest signs of emotional and social growth.

3. Mimic their sounds — Babies learn social cues by copying your reactions.
4. Smile often — Your baby mirrors emotions; seeing your smile teaches them joy.

When to Check with Your Pediatrician#

All babies develop at their own pace, but mention it to your doctor if your baby:

• Doesn’t smile by 3 months
• Avoids eye contact consistently
• Shows limited interest in social interaction

These could simply be signs of a different developmental timeline, but your pediatrician can rule out hearing or vision issues.
