Newborn constant hunger cues: why, and what to do

What's probably happening

At 0–8 weeks, a fed baby that keeps cueing for more usually reduces to one of these — in rough order of likelihood:

• Cluster feeding. Stacked short feeds, mostly 5–10pm. Biologically normal — newborn appetite spikes in the evening and the close feeds drive supply.
• Growth spurt. 2–3 days of marathon feeding around weeks 2–3 and week 6. Then it eases.
• Comfort sucking. Newborns suck for regulation as well as for nutrition. The cue can look identical to hunger.
• Short or inefficient feeds. A sleepy feed or shallow latch leaves them hungry sooner.

When to escalate

See a doctor when you can:

• Not back to birth weight by 2 weeks.

Get immediate medical care:

• Fewer than 5 heavy wet nappies in 24 hours after day 5.
• Brick-dust orange or red colour in the nappy after day 4.
• Fever > 38°C in a baby under 3 months.
