Week 11 at a glance
Development: Deliberate reaching, laughing out loud possible, raspberry blowing, tummy time push-ups · Sleep: 13–14 hours/day — some babies begin 5–6 hour night stretches · Feeding: 5–7 feeds/day · Wake windows: 60–75 minutes
Week 11 of 12 · Month 2
Sleep may improve significantly this week for many babies. If not, it's still within normal range.
Week 11 marks a visible developmental leap. Social engagement accelerates — you'll notice more deliberate eye contact, your baby initiating "conversations," and genuine delight at familiar faces.
At 11 weeks, color vision is still developing — high-contrast black-and-white toys are more stimulating than pastels. Color vision reaches adult-level saturation by around 4 months.

💡 Parent Tip
Offer high-contrast black-and-white images or toys — baby's color vision is still developing. Strong contrast is most stimulating.
🔬 Did You Know?
Color vision reaches adult levels by around 4 months. Before that, babies perceive colors but with less saturation — high contrast patterns are more visually engaging than pastel colors.
An 11-week-old typically sleeps 13–14 hours per 24 hours. This breaks down to approximately 9–10 hours at night (in 2–4 stretches) and 4–5 hours across 4–5 naps during the day. If your baby is sleeping significantly less than 12 hours total and seems unsettled, discuss with your pediatrician.
Not a strict clock schedule — but wake windows work well at 11 weeks. A consistent morning wake time plus naps based on 60–75 minute windows creates a predictable pattern without forcing a schedule a baby isn't developmentally ready for. See the wake windows guide.
Yes — fully normal. Laughter typically emerges between 12–16 weeks. Social smiling in response to your face and voice should be consistent at 11 weeks. If there is no social smiling at all (not responding to faces, not making eye contact), mention this to your pediatrician at the next visit.
Most babies don't sleep a full 8-hour "through the night" until 6 months or later. At 11 weeks, a 5–6 hour stretch is a meaningful milestone. A 4-hour stretch is still normal. Full consolidation typically happens between 4–9 months depending on the baby's feeding needs and neurological development.
Very common at 11 weeks. Contact napping is biologically normal in the newborn period. Independent napping typically becomes achievable after 4 months when sleep architecture matures. If it's unsustainable now, gradual transfer methods work better than sleep training at this age.

Weeks 12–16: sleep starts consolidating, the world opens up
Week 12 brings the first real smiles on demand. Week 16 brings the 4-month regression. Read both so you're ready.
