When should I be concerned about a baby's weight gain?

Typical weight patterns and red flags

Babies often lose up to 7–10% of birth weight in the first few days but should regain birth weight by about 10–14 days. After that, steady weight gain following percentile trends on growth charts is expected.

Warning signs include:

• Failure to regain birth weight by two weeks.
• Sudden or sustained weight loss.
• Very low number of wet diapers or signs of poor feeding.

What to do if growth seems slow

Bring concerns to your pediatrician who can assess feeding, growth curves, and possible causes like tongue-tie, inadequate intake, or medical conditions. Interventions might include feeding support, lactation consultation, formula supplementation if needed, or further medical testing. Early action usually resolves many feeding and growth problems.
