Cooing Begins!
Your baby is much more alert now. Days are filled with sounds, smiles, and long stretches of eye contact. Your little one "responds" when you talk.
Development
- Makes sounds: "Aah," "goo" — your baby responds to your voice
- Smiles intentionally at familiar faces
- Lifts head 45 degrees during tummy time and holds it briefly
- Discovers their hands — stares at them and brings them to their mouth
- Mental leap (week 8): Discovers patterns, and may be fussier for a few days
Growth
- Boys: Average 11.5 lbs / 23.2 in (5.2 kg / 59 cm)
- Girls: Average 11.0 lbs / 22.4 in (5.0 kg / 57 cm)
Sleep
- 14–16 hours per day
- Longer wake windows, often 1–1.5 hours at a time
- May sleep 4–5 hours in a row at night
Feeding
- 6–8 feeding sessions per day — your baby feeds more quickly now
- Growth spurt commonly occurs around 6–8 weeks
- Vitamin D: Continue with 400 IU (10 micrograms) daily
Good to Know
- Hands are a discovery: Your baby stares at them, brings them together, and sucks on their fingers
- Your baby now clearly distinguishes between familiar and unfamiliar faces
- Smiling and "conversations" with your baby support language development
Activity Tips
Hold a colorful rattle in front of your baby and move it slowly from side to side. Watch how your baby tracks it with their eyes — and maybe tries to reach for it.

Tip: Talk to your baby a lot. Narrate what you're doing — tone and rhythm build the foundation for language.
