1. First Week Diaper Progression

In the first week of life, diaper output increases day by day as feeding volumes grow:

  • Day 1: At least 1 wet diaper, 1 meconium stool.
  • Day 2: At least 2 wet diapers, 2 dark/transitional stools.
  • Day 3: At least 3 wet diapers, 2-3 greenish-brown stools.
  • Day 4: At least 4 wet diapers, 3 transitional/yellow stools.
  • Day 5+: At least 6 wet diapers, 3-4 mustard-yellow stools daily.

2. Stool Color Transitions

Meconium (dark tar-like stool) transitions through greenish-brown to classic golden mustard yellow by day 4 to 5.

3. Diaper Rash Prevention & Skin Care

Clean gently with warm water, allow skin to air-dry completely, and apply a zinc oxide barrier cream at the earliest sign of redness.

4. When to Consult Your Pediatrician

Contact your doctor if you notice fewer than 6 wet diapers after day 5, brick-dust reddish urate crystals after day 3, or signs of dehydration.
