1. Physical Growth and Appearance

  • Weight & Height: Babies typically lose a little weight after birth but regain it within two weeks. Expect a weekly gain of 5-7 ounces.

  • Head Shape: Birth can temporarily affect head shape, but it usually rounds out within a few weeks.

  • Skin Changes: Dry or peeling skin, newborn acne, or rashes are common and generally temporary.

2. Reflexes and Movements

  • Moro Reflex: Also known as the startle reflex, where babies throw out their arms in response to loud noises.

  • Rooting Reflex: Helps babies turn their heads toward touch and find the breast or bottle.

  • Grasp Reflex: Babies instinctively hold onto objects placed in their palms.

  • Jerky Movements: Motor skills are still developing, so expect uncoordinated movements.

3. Feeding and Digestion

  • Frequent Feedings: Expect feedings every 2-3 hours, whether breastfeeding or formula feeding.

  • Bowel Movements: Transition from dark meconium to yellow, seedy stools (breastfed) or more formed stools (formula-fed).

  • Spitting Up: Mild reflux is normal as the digestive system develops; excessive vomiting should be monitored.

4. Sleep Patterns

  • Total Sleep: Newborns sleep 14-17 hours daily in short bursts of 2-4 hours.

  • Day-Night Confusion: Babies take time to establish a sleep cycle.

  • Safe Sleep: Always place babies on their back to sleep and avoid loose bedding to reduce SIDS risk.

5. Sensory Development

  • Vision: Babies see up to 8-12 inches and prefer high-contrast colors and faces.

  • Hearing: Recognizes parents' voices and reacts to sounds.

6. Emotional and Social Development

  • Bonding: Physical touch and feeding strengthen emotional security.

  • Crying as Communication: Babies cry to signal hunger, discomfort, or need for attention.

  • First Smiles: Reflexive at first, but social smiles may appear by the end of the first month.

7. When to See a Doctor

Monitor your baby’s health and consult a doctor if you notice:

  • Poor feeding or significant weight loss

  • Extreme sleepiness or lack of response to stimulation

  • Persistent vomiting, diarrhea, or constipation

  • Difficulty breathing or bluish skin tone

  • Lack of reflexes or excessive limpness

By 6-8 weeks, some babies may start sleeping longer stretches at night, but each baby is different.
