Newborn Week 8: What to Expect
Your baby's development, feeding, sleep, your postpartum body, mental health, and what to watch for this week.
What your baby looks like at week 8
Steady chunking. Smiles freely. Looks alert and engaged during wake windows. Many babies are in 3- or 6-month clothes. Cheeks are fuller, eyes brighter.
Baby's development this week
Social smile reliable. Brief belly laughs. Tracks across midline easily. Holds head steady when supported on parent's shoulder. Tummy time tolerance ~5–10 min, with head lifted 45°. Coos consistently in response to talking. May start to swipe at hanging toys. Pre-grasp emerging (open hands, swipes).
Feeding at week 8
7–8 feeds per 24. Most babies have settled into a 5–6 feed daytime + 2–3 night feed pattern. Breastfed: 4–5 oz volume equivalent per feed. Formula: 4–5 oz, 6–7 times daily. Total intake roughly 24–32 oz/day. Spit-up declining for many.
Sleep this week
13–15 hours per 24. 6–8 hour overnight stretch reliable for many (though not all). 3–4 naps per day. Wake windows 90–120 min. Continue 1-arm-out or sleep sack transition if not already done. Continue back-sleep. Many parents move baby to their own room around now (though AAP recommends room-sharing through 6 months — but the official guidance and real-life choices often diverge here).
How your body is doing
Around 2 months postpartum is when many returning-to-work moms have their last 2–3 weeks of leave. Use them well. Don't try to "deep clean" or "use the time productively." Rest, bond, sleep, eat well. Your future self at 4 months postpartum will thank you.
Your mental health this week
Postpartum mental health: PPD onset peaks at 2–3 months for many. If you're starting to feel worse, not better, that's a signal. Reach out. SSRI compatible with breastfeeding include sertraline (Zoloft) — the most-prescribed for postpartum moms.
When to call the pediatrician
2-month vaccines may cause low-grade fever (acetaminophen OK with pediatrician approval, weight-based dose), fussiness, sleepiness for 24–48 hours. Fever >102.2°F or persistent fussiness beyond 48 hours = call pediatrician.
Survival tips for week 8
Set up a vaccine recovery plan: acetaminophen on hand (pediatrician-approved dose, weight-based), keep the next 24–48 hours quiet, plan extra naps and an earlier bedtime. Tummy time 5x daily for 5–10 minutes each. Talk during diaper changes — narrate everything to wire up language centers. Read board books. Get outside daily for sunlight and circadian-rhythm support. Many parents notice a "leap" in baby's awareness around this week.
For your partner
Plan the 2-month vaccine day together — take time off work if possible, hold and comfort baby during shots, let mom rest. Acknowledge it's an emotional day (the first big shot round always is). Take over evening duties for the vaccine-recovery 24 hours so mom can sleep.
Pediatric visits this week
2-month well-check is THIS WEEK. Big weight/length plot, developmental check, lots of questions. Vaccines: DTaP, Hib, IPV, PCV13, RV (oral), HepB possibly (if not done at birth). Lots of shots; bring baby in something easy to undress. Soothe with feeding + cuddles after.
Gear focus
Consider: a stash of acetaminophen drops (pediatrician-approved dose), structured bottle stock for daycare, a comfort lovey introduced (NOT for sleep yet — for short cuddle moments only).
Is this normal?
If your baby is sleeping less well after vaccines or growth spurts, that's normal. Don't change everything in response. Hold the routine and ride the wave.
