Sleep Consolidation
Sleep begins consolidating into longer stretches. The 4-to-3 nap transition often begins here. A common "sleep regression" window. Source: Sleep Foundation, AAP.
At 5 months, babies typically need 12–15h of total sleep, including 10–11h at night and 3–4h of daytime naps (3 naps). Many babies start sleeping through the night.

Planning targets for this age range
| Age Range | Schedule | Before Nap 1 | Before Nap 2 | Before Nap 3 | Before Bedtime |

Common sleep challenges at this age
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.
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.
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.

Follow safe sleep guidelines: place babies on their back on a firm, flat surface with no loose bedding.
