Common Myths — Busted

Myth: Babies should be bathed daily
Truth: Bathing 2-3 times a week is sufficient for infants, as over-bathing can strip their skin of natural oils.
Myth: All newborns have blue eyes
Truth: Newborn eye color can appear blue due to lack of pigmentation, but actual eye color may emerge around 6-12 months.
Myth: Babies can see clearly at birth
Truth: Newborns have limited vision, around 20-30 cm, which improves to 1-2 meters by 6 months.
Paediatrician’s tip: Monitor your baby’s growth by tracking their weight, length, and head circumference every month, as this helps identify any potential growth issues early on.
Reassurance: It’s normal for babies to lose up to 10% of their birth weight in the first week, and they typically regain it by 2 weeks of age.

When to See Your Paediatrician

  • Fever above 38 degrees Celsius
  • Weight loss or failure to gain weight for 2 consecutive weeks
  • Vomiting more than 5 times a day
  • No bowel movement for more than 3 days
