Sleep Disruption Troubleshooting

Common sleep challenges at this age

Teething Pain

When: Can begin around 4–6 months and continue through 24 months as teeth erupt.

Signs: Increased drooling, gum rubbing, irritability, refusal to feed, disrupted night sleep.

What helps: Offer a clean, chilled teething ring. Gently massage gums with a clean finger. Maintain consistent bedtime routines. If pain is severe, consult your pediatrician about appropriate pain relief.

Night Feed Changes

Newborns (0–3m): Feed every 2–3 hours around the clock. Night feeds are essential.

3–6 months: Fewer night feeds needed. Some babies sleep 8+ hours. Source: NHS.

6+ months: Many babies can sleep 6–8 hours without feeding. Solids complement milk. If night feeds were sleep associations, gradual weaning may improve sleep, but consult your pediatrician first.

Separation Anxiety

Peak windows: Around 8–10 months and again at ~18 months.

Signs: Crying when you leave the room, bedtime resistance, waking and needing your presence to resettle.

What helps: A consistent, calming bedtime routine signals safety. Object permanence development is healthy. Brief check-ins with soothing words can help. Avoid prolonging nighttime interactions. Source: AAP.

Growth Spurts

Common at: ~3 weeks, 6 weeks, 3 months, 6 months, and 9 months (timing varies).

Signs: Increased hunger, more frequent waking (day and night), possibly fussier than usual.

Duration: Usually 2–7 days. Follow baby's hunger cues. Temporary increase in feeds is normal. Sleep typically returns to baseline after. Source: AAP.

Developmental Milestones

Common milestones: Rolling (~4–6m), sitting (~6m), crawling (~7–9m), pulling to stand (~9–11m), walking (~12–15m).

Impact: Babies may practice new skills at night, leading to disrupted sleep. Some may seem to "forget" how to sleep for 1–2 weeks.

What helps: Provide plenty of practice time during the day. Maintain routines. If baby gets stuck in a new position, gently help them resettle without fully picking them up.

Medical Disclaimer: This tool provides general reference information compiled from pediatric sleep guidelines (AAP, Sleep Foundation, NHS). Every baby develops differently. These are typical ranges, not prescriptive targets. Always consult your pediatrician for questions about your baby's feeding, growth, health, or sleep concerns. Follow safe sleep guidelines: place babies on their back on a firm, flat surface with no loose bedding.
