  • DHA: fatty fish 2-3×/wk
  • Hydration to thirst (~3 L/day)
Foods to limit
  • Caffeine > 200 mg/day
  • Alcohol (limit; if any, BF after 2 h/drink)

Monitor + cadence
What to track
  • Infant weight gain (15-30 g/day weeks 0-3, 100-200 g/week after)
  • Maternal hydration + energy
  • Wet/dirty nappies × 6+/day from day 5
  • Self-screen mastitis (red breast, fever, malaise)
Red flags — seek care
  • Mastitis with fever → urgent antibiotics + continue BF
  • Significant supply drop → IBCLC same-week
