Not eating / feeding dips

When a smaller appetite is normal

Is this normal?

Appetite naturally goes up and down in babies — teething, a growth pause, a mild cold or even a hot day can shrink a feed. As long as baby is having wet nappies and is acting like themselves between feeds, short dips are usually fine.

Why this happens

Babies regulate their intake well over a week, not a single day. Illness, teething and rapid brain growth all temporarily change appetite — it usually self-corrects as soon as they feel better.

What you might see

  • Taking less per feed for a day or two
  • More distracted at the breast or bottle
  • Wanting comfort feeds more than hungry feeds
  • Refusing solids but still drinking milk
