What to Expect in the First 2 Weeks
Weight loss then gain
Normal to lose up to 7–10% of birth weight in week 1. Should regain birth weight by day 14. Call your provider if not regained by 2 weeks.
Sleep: 16–18 hours/day
In short bursts of 2–4 hours. No circadian rhythm yet — nights and days are the same to a newborn. Light exposure in the morning helps establish rhythm.
8–12 feeds per day
Breastfed babies feed more frequently than formula-fed. Feed on demand — not by the clock. Frequent feeding establishes milk supply.
Jaundice is common
60% of newborns develop some yellowing in days 2–4. Mild jaundice is self-resolving. Severe jaundice needs phototherapy. Your midwife will monitor.
Settling Your Newborn
The 5 S's (Dr. Harvey Karp) are evidence-based settling techniques that mimic the womb environment:
- Swaddle — arms in, snug but not tight around hips. Stop swaddling when baby shows signs of rolling.
- Side/Stomach position — held on their side or stomach (never for sleep). Activates the calming reflex.
- Shush — loud white noise (louder than you'd expect — the womb is loud). Apps like Calm or simply a white noise machine work well.
- Swing — fast, jiggling movement (like a car ride). Slow rocking actually understimulates the vestibular system.
- Suck — breast, finger, or pacifier. Sucking activates the calming reflex strongly.
